Are there any removal tools for help with the removeal of .net 2.0 beta components? I've seem to come across a problem with removing SQL '05 Express Beta and now i can't get it reinstalled.

You should consider using an extension for the EXE that at least defaults (both on the server and in clients) to a binary MIME type, so that if a user simply clicks on it they will be prompted to download it. You could use a real extension like .zip (and zipping the EXE would reduce size) or (if WinISP supports it, and I honestly don't know it if will) .bin (which typically defaults to "application/octet-stream" for unknown and/or unmapped extensions).

Mike - we are actually in the process of getting a version of this tool ready for the Whidbey .NET Framework also. There are a couple of fixes I need to make to fully enable this for all of the beta and community tech preview versions of the .NET Framework 2.0 that are out in the wild. Stay tuned, I'll post an update to my blog when I have something ready to try out.

Heath - thanks for the posting suggestions. I could've sworn I had tried to upload a ZIP file to the WinISP site and it failed in the past. But I just tried again and it worked. So I'm going to update the text of this blog item to reflect the new link.

Thanks for having a go. I ran this but still can't install .net 1.1 via dotnetfx.exe on xp pro. I have tried all other MS and your suggestions but to no avail. Looking at the MSI .log it fails at Registering System.EnterpriseServices.dll:

re: Removal tool to fix .NET Framework install failures

astebner — Sat, 04 Jun 2005 22:04:28 GMT

Hi Dave, we have gotten a lot of reports of .NET Framework installation errors where the failure occurs when trying to register System.EnterpriseServices.dll. Unfortunately we have not found a consistent root cause for this. In a lot of cases running my cleanup tool will help, but in many others it will not.

The tricky part here is that registering this DLL is the first time that the underlying CLR is used to run managed code, and so if any part of the CLR is not working then this action will fail. But there are many possible causes for the CLR to not be working when it is being installed.

I am working on a blog post describing how to gather debugging information from this action during setup to aid us in figuring out the root cause. I will post a link to it once I get my steps tested and posted on my blog....sorry for the delay.

I am having problems installing .net Framework 2.0 on an XP pro machine, this error keeps comming up:
Error 25015.Failed to install assembly
'C:\Windows\Microsoft.NET\Framework\v2.0.50215\Microsoft.VisualBasic.Vsa.dll' because of system error: Access is denied.

Any ideas on what can be causing this, the installer works fine on other machines but this one seems to fail (ofcourse its the machine i need it on). Any help is greately appreciated!

re: Removal tool to fix .NET Framework install failures

astebner — Tue, 07 Jun 2005 23:39:07 GMT

Hi Dmitry,

This error sounds like it could be a permission issue for the global assembly cache. Can you please try the following:

1. Open the %systemdrive% folder (normally this is c:\) in Windows Explorer
2. Right-click on the Windows folder and choose Sharing and Security
3. Choose the Security tab
4. Click the Advanced button
5. Make sure that Users are listed as having Read & Execute permissions, Administrators have Full Control and SYSTEM has Funn Control
6. Check the box that says "Replace permission entries on all child objects with entries shown here that apply to child objects"
7. Click the OK button
8. Try to install .NET Framework 2.0 again

If that does not work, can you please try the following:

1. Download the Filemon utility from http://www.sysinternals.com/Utilities/Filemon.html and install it
2. Launch Filemon and press CTRL + L to launch the filter dialog
3. Check the box to log writes and choose to include msiexec.exe and fusion.dll
4. While Filemon is running run .NET Framework 2.0 setup and wait for it to fail
5. Copy and paste the error messages with access denied as the error type and send them to me via email so we can see if we can figure out the root cause

I'm trying to install .Net Framework 2.0 beta 2 onto xp pro sp2 using the redist dotnetfx.exe, version 2.0.50215.45. I get the error message "Error 25015.Failed to install assembly
'C:\Windows\Microsoft.NET\Framework\v2.0.50215\System.EnterpriseServices.dll' because of system error: parameters incorrect". Can you help?

re: Removal tool to fix .NET Framework install failures

astebner — Sat, 18 Jun 2005 01:22:53 GMT

Hi Andy - I've been asking around and nobody here has seen the error you're running into, so I think we may need to use a variation of the debugging steps I just posted at http://blogs.msdn.com/astebner/archive/2005/06/17/430320.aspx to gather more information about your machine. Here are the exact steps that you can use to get crash info:

1. Download and install the .NET Framework 2.0 redist and SDK on a separate machine. You can download them from http://lab.msdn.microsoft.com/vs2005/downloads/netframework/default.aspx
2. Copy the file gacutil.exe from the folder c:\Program Files\Microsoft .NET\SDK\v2.0\bin to the machine where setup fails
3. Download and install the Debugging Tools for Windows. You can download this from http://www.microsoft.com/whdc/devtools/debugging/installx86.mspx
4. Rerun .NET Framework 2.0 setup on the machine that you see this failure
5. During installation, leave the error message up on the screen
6. While the error message is still on the screen, open WinDBG
7. From the File menu, choose Open Executable...
8. In the File name text box, enter the following information: c:\gacutil.exe (or wherever you copied gacutil.exe to in step 2 above)
9. In the Arguments text box, enter the following information: /i c:\windows\Microsoft.NET\Framework\v2.0.50215\System.EnterpriseServices.dll
10. After entering the above information, choose Yes to save base workspace information
11. Press g in the Windbg window to resume execution until the process crashes, then save the crash log to a file

If you can send me the crash file I will try to take a look and see if I can figure out how to fix this.

Fei — Thu, 30 Jun 2005 06:41:46 GMT

Hi,

I'm also having the same error which Dmitri has while installing .net framework 2 beta 2 :

Error 25015.Failed to install assembly
'C:\Windows\Microsoft.NET\Framework\v2.0.50215\Microsoft.VisualBasic.Vsa.dll' because of system error: Access is denied.

I've already tried both things that astebner suggested to do, but still doesn't work. In File Monitor, I didn't find any "ACCESS DENIED" result. I found only "PATH NOT FOUND" results as an error message, it's said that some dll not found in C:\I386.

Any idea?

Thanks

re: Removal tool to fix .NET Framework install failures

astebner — Sat, 02 Jul 2005 04:02:18 GMT

Hi Fei,

First of all, I would suggest making sure that you have disabled any antivirus or anti-spyware applications (temporarily of course) during the course of setup. Sometimes those can interfere with installation and cause access denied errors. However, I would definitely expect to see a message in FileMon for any access denied error, so that is odd.

Do you see a pop-up dialog for this 25015 error? If so, can you try to use the tool gacutil.exe and manually install the assembly to the GAC while that error is on-screen and see if it gives any additional error information. You will need to do the following to try this:

1. Install the .NET Framework 2.0 beta 2 and .NET Framework 2.0 SDK beta 2 on a separate machine (you can get them at http://lab.msdn.microsoft.com/vs2005/downloads/netframework/default.aspx)

2. Copy gacutil.exe from %programfiles%\Microsoft.NET\SDK\v2.0\bin to the other machine where this failure is happening

3. At the point of failure, run gacutil /i C:\Windows\Microsoft.NET\Framework\v2.0.50215\Microsoft.VisualBasic.Vsa.dll and let me know what the output is

Hopefully this helps...

Aaron:

I was just cleaning up my \\desktop and noticed your removal utility lingering thereupon. (I had put it to use on April 30 ... exactly 3 months ago ... so it appears.)

Alas, I owe you very special thanks for finally rectifying a maddening .net botched install ... one which caused me continuous grief at the hands of my antivirus software -- which persistently admonished me for an out-of-date windowsupdate status. (Windowsupdate was unable to apply .net patches ... because of the botched install.)

In any case, I don't know who you are ... but you have my vote for software philanthropist of the year. May good things come to you in abundance.

Thank you,
David

Aaron, Just wanted to let you know I tried the workaround you recommended based on my prior post. This work around solved the problem and I was able to successfully install the 2.0 .NET framework. Sorry I was not more diligent about looking at the other content in your blog.

re: Removal tool to fix .NET Framework install failures

astebner — Fri, 19 Aug 2005 06:45:56 GMT

George - I'm glad that the workaround was successful. It is hard to find all of the random comments I've posted, so there's no need to say sorry. I'm going to try to pull some stuff together into a parent post that serves as kind of a troubleshooting guide with a bunch of sub-links to my other posts, but I just need to find time to get it all typed up :-)

Tpham - I received your email and sent you the following set of steps, which you indicated resolved your issue (I'm posting them here for any others who happen to read my blog):

1. Uninstall the Data Tier
2. Launch SQL Management Studio
3. Delete all of the following databases if they exist:
BisDB
BisDWDB
CurrituckDB
ELeadDB
Psshared
VSTEAMSCC
VSTEAMSCCAdmin
4. Re-run Data Tier setup

If you are performing a single server setup, you will need to do all of the above plus the following additional step:

5. Uninstall ADAM (this can be done before or after uninstalling the Data Tier)

Ron — Wed, 31 Aug 2005 22:50:54 GMT

Hi Aaron -

Thanks for all your efforts on this blog, I found it extremely useful, and came close to solving my .NET Framework problems, but fell shy of the solution. I am guessing, given your new job, that you will know the answer handily.

After much effort, I found I needed to use your clean-up tool to remove 1.0 and 1.1. The good news is I can easily re-install 1.1, but the program that asks for the original source CD to install 1.0 would not correctly recognize my MCE 2005 CD.

How can I re-install .NET Framework 1.0 on an MCE 2005 machine?! Are there manual steps listed somewhere, or a way to force msiexec to recognize the original install CD/netfx.cab?

Thanks,
Ron

re: Removal tool to fix .NET Framework install failures

astebner — Fri, 02 Sep 2005 06:32:49 GMT

Hi Ron - .NET Framework 1.0 is installed as part of the operating system on Windows XP Media Center Edition (and Tablet PC edition). Therefore you cannot re-install it by simply running the dotnetfx.exe package or any msiexec command lines.

The instructions for repairing the .NET Framework 1.0 that comes as part of the OS on MCE and Tablet are a little bit complicated, so I posted a separate blog item about this, you can find it at http://blogs.msdn.com/astebner/archive/2005/09/01/459631.aspx.

I know they are kinda convoluted, so if you have any issues please don't hesitate to contact me at aaronste (at) microsoft (dot) com and I will do my best to assist you....

Where would I find the program for the NET FRAMEWORK INSTALLER on the windows CD.

hope this makes sense.

re: Removal tool to fix .NET Framework install failures

astebner — Tue, 22 Nov 2005 20:13:10 GMT

Hi Dan - If you have a CD with XP Pro with SP1 integrated, you can find the .NET Framework 1.0 in the dotnetfx folder in the root of the CD. If you have a CD with XP Pro with SP2 integrated, you can find the .NET Framework 1.1 and 1.1 SP1 in the dotnetfx folder in the root of the CD.

Also, you can download the .NET Framework from the web as a standalone package. Check out the links at http://msdn.microsoft.com/netframework/downloads/updates/default.aspx.

****ERROR**** Cleanup failed for product .NET Framework - Both Versions

The above error was the last line in the cleanup_main.log file created when using your tool.

I just bought two Wrox books on ASP.NET programming and will be installing the following on my Windows XP SP2 machine:

1) Microsoft .NET Framework Version 2.0
2) Visual Web Developer 2005 Express Edition
3) Microsoft SQL Server 2005 Express Edition

My PC already had .NET Framework 1.0 and 1.1.

I tried removing both via Add/Remove Programs but the process never completed.

I thought I had to remove them before I installed 2.0 -- was I wrong?

What should I do know? Thanks in advance.

re: Removal tool to fix .NET Framework install failures

astebner — Tue, 29 Nov 2005 07:55:28 GMT

Hi McKirahan - I'm sorry for the hassle here. The first important thing to mention is that the .NET Framework 1.0, 1.1 and 2.0 are designed to be side-by-side, so you can definitely have all 3 versions installed at the same time.

I think the best route to go now that you have tried to remove 1.0 and 1.1 is to use the instructions that I posted at http://blogs.msdn.com/astebner/archive/2005/10/11/479928.aspx to clean and reinstall both 1.0 and 1.1, and then install 2.0 and the WebDev and SQL 2005 Express editions.

Please contact me at http://blogs.msdn.com/astebner/contact.aspx if you run into any issues getting these steps to work...

I don't know if you got this submit:

Dear Aaron,

HUGE THANKS! I have to praise (big praise) you SO much for your gift of that cleanup tool!!! I went through all the steps to try to find out why the MS update failed in two new machines I was installing for husband/self. I had started getting errors like those noted in some of your blog pages, and that type of thing is a major warning to "cleanup."

I tried walking through the long drawn out fix offered at the MS site (having drilled through many URLS until I got there) and THEN I got stuck on the fix because files/dirs they said to delete would not delete!

Ultimately, I couldn't figure out why a security download would NOT install and I wanted that security. I was JUST about to give up after 3 hours into this, when I found YOUR page and downloaded this cleanup tool. Long story short, NOTHING worked until I used your cleanup tool.

For those who might be stuck like I was... Here were my steps to overcoming this "painful" problem (many thanks to Aaron's help!):

1. Downloaded/extracted the dotnetfx.exe files into a dotnet directory/folder on drive C like this (thanks to Aaron). Start\Run then typed in: dotnetfx.exe /t:c:\dotnet /c

2. I used Aaron's "Cleanup tool" dotnetfx_cleanup_tool.zip by simply opening the zip and running cleanup_tool.exe This worked like a charm.

3. Then ... to install .NET Framework 1.1 I went to my "dotnet" directory and double clicked: netfx.msi

PARTIAL VICTORY!

NOTE: I went to the following to download...

Security Update file: NDP1.1sp1-KB886903-X86.exe

Microsoft's notes:
"ASP.NET Security Update for Microsoft .NET Framework 1.1 Service Pack 1"

I attempted to install NDP1.1sp1-KB886903-X86.exe
and got this message:

"COULD NOT INSTALL NDP1.1sp1-KB886903-X86.exe with this error message:

SO...I went back to the MS Windows update site...

4. I still had KB886903 update to install. I did so...and Bingo.

Done.

Aaron, I wouldn't have gotten there without your help. This type of problem is COMPLETELY obnoxious and a time waster. Even so...I would not have been able to resolve this without your hard work and I thank you!

Issues with .NET framework 1.1 installation

Stephen Adams — Thu, 05 Jan 2006 18:29:15 GMT

Hello Aaron! I'm on my last leg here. :(

Just recently built a new computer. XP SP2 running an A64 chip. I
installed Visual Studio 2003 and Visual Studio 2005 and as part of the
prereqs, both v1.1 and v2.0 of the framework respectively. I was able
to compile and run web applications, but after compiling and running a
windows application from either Visual Studio I received a "Application
failed to initialize properly." error everytime no matter what
application I compiled. My web apps worked, but my windows forms
didn't. Strange. This led me to believe it was a possible corrupted
framework problem.

So I uninstalled the v1.1 framework and tried reinstalling, but
everytime I got this message:

"NET Framework 1.1 Setup has ended prematurely"

This happens right at the very last step when trying to setup
System.EnterpriseServices

I've tried renaming mscoree.dll, removing all the .NET components,
running clean up tools, and everytime I run the 1.1 framework installation it won't install. It keeps failing at the very, very, very last step. :(

PLEASE, PLEASE help me here. I need to have these development environments
installed. They were installed before, but I had to uninstall them to
fix this problem, and now I can't even install the .NET frameworks.

I've never seen this issue before and I've been reading all over, and
every thing I'm told to do doesn't work. I just need a clear cut
solution to remove the .NET framework remnants and clean anew WITHOUT
having to reformat.

Thanks much Aaron, hopefully you can help me. :)
-Steve

Hi Marcus - Thank you for posting the workaround that worked for you. I have seen this workaround solve other issues as well, so I created a new blog post to describe this workaround. It is located at http://blogs.msdn.com/astebner/archive/2006/01/08/510677.aspx

Hi Stephen - can you please try this workaround and see if it helps for you? If not, there are a couple of other suggestions listed in that blog post for other possible fixes for this error in .NET Framework 1.1 setup.

Access Denied error installing Framework 2.0 Microsoft.VisualBasic.vsa.dll

Derek — Mon, 16 Jan 2006 14:25:27 GMT

I was receiving an error installing the 2.0 Framework with an 'Access Denied' error on the file Microsoft.VisualBasic.vsa.dll and I thought I would post the solution I found as other people have been encountering it.

By using FileMon, I could see that the ACCESS DENIED error was actually being return when the setup tried to create the file GACLock.dat in the folder c:\winnt\assembly

For some reason, Administrators had lost permission to write to this folder.

I was not able to apply permissions using Windows Explorer, but could set Administrators to having full control in this folder by using the following CALCS command from the command line:

calcs c:\winnt\assembly /E /P BUILTIN\Administrators:F

After this the framework installed OK.

re: Removal tool to fix .NET Framework install failures

Zan — Tue, 17 Jan 2006 22:59:17 GMT

Hi,

I'm using Windows XP x64. I am trying to uninstall Microsoft .NET framework x64 BETA 2 (Shipped with VS 2005 BETA). The framework seems to have had installed a couple of important files in 'Program Files (x86)' which contains, due the uninstaller, 'illegal characters' (the parantheses?). Because of this issue I can't uninstall Microsoft .NET framework x64, which I have to do in order to be able to install VC++ Express Edition.

The only error message I get is:
'Error 1324.The folder path 'Program Files' contains an invalid character.'.

Is it possible to change the registry keys somewhere from 'Program Files (x86)' to perhaps 'Progr~2'? Or is there another method?

re: Removal tool to fix .NET Framework install failures

astebner — Wed, 18 Jan 2006 01:11:32 GMT

Hi Zan - I don't think the parentheses is an invalid character since Windows allows you to create a folder with that name. Can you please try the steps listed at http://blogs.msdn.com/astebner/archive/2005/10/30/487096.aspx to try to manually remove the .NET Framework 2.0 beta that you have on your system? Hopefully that will get you past this error.

AndyC — Sat, 11 Mar 2006 21:04:46 GMT

Guys,

I've solved this problem. I had to remove all my framework versions and then in my Windows/Assembly directory I had some existing subdirectories that needed clearing out, including GAC_32 and GAC_MSIL.

I'm not sure what happened along the way to cause this problem, as I had hoped to run different framework versions alongside each other. But thanks to Aaron, using your manual uninstall process got everything working again.

Thanks,
AndyC

CRM Outlook Client Install failure

Steve Yates — Fri, 17 Mar 2006 06:41:38 GMT

Hi,

We have one PC that gets the following error in the Microsoft CRM 3.0 Outlook Client installer, and can't get past the system requirements phase of the installation:

"Microsoft CRM Client for Outlook Setup User Input File or assembly name 9o3db28v.dll, or one of its dependencies, was not found."

(the file name is random and changes on every installation attempt). Any suggestions? Do you think removing the .NET Framework might help? The user is a local administrator and has rights to the user and system Temp folders.

re: Removal tool to fix .NET Framework install failures

Jmonkey — Sun, 19 Mar 2006 00:25:35 GMT

I used the uninstaller "ttool.exe", but all it did was remove my newest version of .net framework 2.0. I'm looking for a tool to remove the beta 2 versions. I HAVE BEEN POINTED TO MICROSOFT ALREADY... I do not have any uninstallers. I have the installer that links to a dead end, therefore, I will never be able to get the uninstaller back. Is there anyone who has a list of the registers and folders so I can remove them myself, or is there a better program than the two similar ones from Microsoft. The one on their page gives me error message saying I might not have access to them if I am not an Administrator, but of course, I am... anyone who has the best way to remove these programs, can you think of a way without hurting my .net Framework 1.1 or 2003 registered version?

re: Removal tool to fix .NET Framework install failures

astebner — Sun, 19 Mar 2006 01:17:18 GMT

Hi Jmonkey - Can you please try to use the instructions listed at http://msdn.microsoft.com/vstudio/support/uninstall/default.aspx to determine a list of the exact products you need to uninstall, and then use the individual Add/Remove Programs entries for each of those products?

re: CRM Outlook Client Install failure

Steve Yates — Sun, 19 Mar 2006 09:16:57 GMT

Hi Aaron, the installer is part of CRM. The complete path we're using is this:

msiexec.exe /i "\\SERVER1\ClientApps\MSCRM\DesktopClient\lightclient.msi" CONFIG="\\SERVER1\ClientApps\MSCRM\DesktopClient\default_client_config.xml"

...however, copying the folder to the workstation and installing from there yields the same result.

re: Removal tool to fix .NET Framework install failures

Jmonkey — Tue, 21 Mar 2006 03:28:17 GMT

Again, let me reitterate what I just wrote... I DO NOT HAVE THE UNINSTALLERS.... I've also tried 2 versions of Microsoft's uninstaller on that page and the one on one of this website's pages. It says I do not have rights or something like that because I am not an Administrator. But I am! I own the computer. I don't have uninstallers, but I still have registers and assemblies and some hidden files in directories. I can remove the 8.0 version in program files, but there is much more to remove in sys32 in %windir% etc... I need to do this manually it looks like. ADD/REMOVE programs is out of the question. I have a registered version of 2003 in there, so I don't want to hurt it. Any suggestions besides the obvious?

I have the June version of SQL Server to install, but I need to remove the betas first. I don't want to do it by myself so that I don't delete needed files or registers of my 7.1 version. Some is obvious, some isn't, some is hidden. Any manual suggestions? Or if there's a 3rd BRAND NEW PROGRAM, NEW AS OF released today or anytime hereafter...any help beyond what is on main microsoft website is gratefully appreciated... Thanks again!

re: Removal tool to fix .NET Framework install failures

astebner — Tue, 21 Mar 2006 03:42:57 GMT

Hi Jmonkey - I am not sure I understand your comment saying "I do not have the uninstallers" - does this mean that none of the beta VS 2005 versions show up in Add/Remove Programs at all? If that is the case for you, can you please try to Can you please try to use the instructions listed at http://msdn.microsoft.com/vstudio/support/uninstall/default.aspx to determine a list of the exact products you need to uninstall, and then use the steps listed at http://blogs.msdn.com/astebner/archive/2005/10/30/487096.aspx to locate and manually remove each of them. Hopefully this helps.

I would also be curious to know how your machine got into the state it is in. I haven't ever heard of a case where every entry disappeared from Add/Remove Programs like that (in the case of VS 2005, it installs somewhere between 5-10 different Add/Remove entries). Have you done anything like a system restore recently that might explain the things disappearing from Add/Remove Programs like that?

Hi Steve - can you please use the steps listed at http://blogs.msdn.com/astebner/archive/2005/03/29/403575.aspx to gather verbose logs for this setup and contact me via http://blogs.msdn.com/astebner/contact.aspx so I can see if I can figure anything out from the logs?

re: Removal tool to fix .NET Framework install failures

astebner — Tue, 21 Mar 2006 03:53:56 GMT

Hi Jmonkey - I am sorry, it looks like you posted your last question as I was typing my previous reply, so I didn't see it at the time. The .NET Framework 2.0 is a prerequisite for Visual Studio 2005, so you will have to have it installed if you want to install VS 2005. You will need to make sure you are installing the final release of VS 2005 and not one of the old beta versions though, because the final release of the .NET Framework 2.0 will only work with the final release of VS 2005.

re: Removal tool to fix .NET Framework install failures

Jmonkey — Tue, 21 Mar 2006 05:31:56 GMT

You know why I ask...I have cd's sent to me from Microsoft with SQL 2005. And isn't SQL 2005 a prereq to install Visual Studio 2005...? I try installing it, it's a June 2005 Community Edition Release, and it tells me this reason...it goes first, followed by Visual Studio, then the framework. I know by Visual Studio 2003 Windows SP2 and framework 1.1 and a few other things were first. Maybe I read the page wrong...

re: Removal tool to fix .NET Framework install failures

astebner — Tue, 21 Mar 2006 06:58:48 GMT

Hi Jmonkey - You cannot mix and match beta builds with final released builds. It sounds like the CDs you have with SQL 2005 are from a beta version, so it will not install correctly if you have the final release of the .NET Framework 2.0 installed (because the .NET Framework 2.0 is a prerequisite for SQL 2005). The .NET Framework 2.0 is a prereq of both VS 2005 and SQL 2005, and will need to be installed before installing either of those other products.

However, SQL 2005 is not a prerequisite for installing VS 2005. There is a version of SQL 2005 (SQL Express) included in VS 2005 setup, but it is an optional component and is installed after VS 2005.

Luis — Tue, 28 Mar 2006 19:29:31 GMT

Hi Aaron.
First af all, excusme for my bad english.
My problem is:
I had the Microsoft .NET Framework 1.1 and the Microsoft .NET Framework 1.1 Hotfix (KB886903) installed on my Win XP Pro SP2.
I uninstalled them in a wrong way: First, in Add/remove Programs, I unistalled the Hotfix, but WITHOUT restarting the machine, and then I uninstalled the Microsoft .NET Framework 1.1.
This was fatal.
Now, each time I start Wondows tow little error windows appears. I accept the two windows and the Win XP works.
I tried to uninstall again with Add/remove Programs: Dont work.
I tried to uninstall and repair with the Installer: Dont work.
So, I can not unistall, repair or reinstall the Microsoft .NET Framework 1.1

I want to unistall the Microsoft .NET Framework 1.1.
What can I do?
Can I try your tool?

Thanks in advance.
Luis.

You mentioned that you were going to get a KB article written up with a copy of the cleanup tool. Have you had time to do that? Some people around here feel more comfortable with us using a tool that is "official"!

re: Removal tool to fix .NET Framework install failures

astebner — Mon, 01 May 2006 20:19:39 GMT

Hi Mgm - I am still talking to the team that writes knowledge base articles to figure out how best to communicate this. Currently, the steps performed by the cleanup tool are listed in existing knowledge base articles as manual steps, and the tool just automates those steps. I understand the greater comfort level with using a tool that is more "official," but for now this is all I can offer...

Hi Jim - I would suggest trying the steps listed at http://blogs.msdn.com/astebner/archive/2005/10/11/479928.aspx to remove and reinstall the .NET Framework 1.1 and see if that resolves this problem.

I have windows xp home edition. I seem to have a problem with my Microsoft.net framework. When i turn on the computer, everything starts loading, but then this box comes up showing: Microsoft,net framework an unhandled exception has occurred in a componant to your application. Also below that it show also: File or assembly name hpqasset, or one of its dependencies, was not found. I would try to hit continue assuming it's gonna fix the problem, then an installer comes up, but it won't let it install, i'm having to get rid of it by hitting ctrl, alt, delete, and when i do it's showing that the installer is running, is the only way i can get rid of the box, because it won't get rid itself, but nothing else helps. Please if anyone has any idea for me to fix this.

Thank You Rican

re: Removal tool to fix .NET Framework install failures

astebner — Thu, 13 Jul 2006 06:43:12 GMT

Hi Rican - I am not sure what the file "hpqasset" is, but it is not a part of the .NET Framework. I think that the error is just being reported by the .NET Framework because the other program is a .NET application. I would suggest trying to find what program the file "hpqasset" is a part of and then repairing that program.

re: Removal tool to fix .NET Framework install failures

webmasta — Tue, 26 Sep 2006 23:53:10 GMT

Quite a tool you have there Aaron... it helped my situation in a way but I am still stuck with this MS PoS they call .NET after a 4 day merry go round.

My issue is that .NET was working on my XP box since 2004 when I installed the whole shebang including the 2003 IDE from an educational CD as part of a .NET course.

Recently a trojan sneaked into my box and all .NET apps failed with 'error 0x0000005' which really doesnt say anything helpful(TM microsoft errors)

Obviously I attempted to reinstall/repair the installation from the original CD with no success, .NET install would fail with 'setup ended prematurely'... which again really doesnt say anything helpful(TM microsoft errors)

Finally I got to understand it was because I had hotfix(kb866903). Trying into uninstall the hotfix was a nitemare itself, just wouldnt go, add-remove would blink and refresh without uninstalling the hotfix.

I got your removal tool which cleared up the 1.1 install but didnt touch the hotfix... same as with the Windows Installer Cleanup utility
from this link:
http://download.microsoft.com/download/E/9/D/E9D80355-7AB4-45B8-80E8-983A48D5E1BD/msicuu2.exe

I followed the steps outlined here:
http://www.experts-exchange.com/Operating_Systems/WinXP/Q_21409539.html
which moved things a bit further on and took the hotfix out of add-remove but really didnt uninstall it completley.

.NET still wouldnt install, 'setup ended prematurely'.

What would you suggest to completly get the hotfix out so that I can do a clean install? (apart from giving this .NET PoS its first flying lesson out of the box and straight through the window?)

Aside from that, I finally learnt that installing with MSI from a CD is total crap since the uninstall info is linked to a .tmp file thats long gone what you try to repair/uninstall. (which bright spark at MS could have dreamed up that crap(TM microsoft))

Thanx/webmasta

Hi Webmasta - I'm very sorry for the experience that you've had with the .NET Framework so far. Error code 5 means "access is denied" and I've seen some cases of this in the past caused by anti-virus scanners and/or some incorrect file permissions. Can you try the workaround listed at http://blogs.msdn.com/astebner/archive/2005/08/16/452523.aspx and if that doesn't help, try the workaround listed at http://blogs.msdn.com/astebner/archive/2006/09/04/739820.aspx?

re: Removal tool to fix .NET Framework install failures

webmasta — Wed, 27 Sep 2006 22:51:02 GMT

Thanx Aaron... I looked over your suggestions and decided to do it my way - brute force and ignorance - simply because I was quite fedup with trying any and every workaround I came across and I wanted to have the option to uninstall in the future.

I cleand up with your tool and also the windows cleanup utility.

I identified anything that had to do with .net and vs2003 and manually deleted - from files, folders all the way to reg entries.

Ran Registry Mechanic to scrub the registry.

Downloaded .net 1.1, the sp1 and hotfix 866903 and installed in that order ... it worked... tried uninstalling and that worked too.

Interesting observation: before all this, add/remove was reporting .net and hotfix at 249MB each, now with the new install they both come in at under 24MB each... where the previous bloat came from is still a mystery.

A few days ago, I installed .NET Framework v1.1 but that generated an error message:

Application has generated an exception that could not be handled.

I used add/remove programs to remove .NET Framework v1.1 and then installed v2.0.

Now I've been getting error messages at startup which point towards .NET. I used add/remove to uninstall .NET Framework 2.0, but Add/Remove Programs still shows two related listings which I'm unable to remove usind Add/Remove:

.NET Framework v1.1

.NET Framework v1.1 hotfix (KB886903)

When I try to remove the first one, I get the message "this patch package could not be opened." When I select and try to remove the hotfix, nothing happens.

I'm getting two error message startup. The first one is:

Fatal Execution Engine Error (0x7927e03e)

The second one (NotifyAlert.ext -- Common Language Runtime Debugging Services):

Application has generated an exception that could not be handled.

Process id=0xbx04(2880), Thread id=0xb08(2824)

Click OK to terminate application

Click CANCEL to debug the application

The id number seems to change in this message on each restart. Hitting Cancel does not allow debug to run.

Any suggestions on how to completely get rid of .NET? I've done some googling on this issue and many suggestions are too extreme for me -- such as reinstalling the OS. I don't want to go down that road unless it's a last resort. The I found your blog which has a link for a .NET cleanup tool but I've been unable to load the page specified in the link or get to the zip file any other way.

Two questions, is it likely that the cleanup tool would remedy my problem and if so, is there somewhere else I could go to, to download the file.

Thank you and sorry my comment has been so rambling. I'm not technical but wanted to provide as much info as possible.

re: Removal tool to fix .NET Framework install failures

kkk — Thu, 30 Nov 2006 14:30:32 GMT

Hello Aaron! I'm on my last leg here. :(

Just recently built a new computer. XP SP2 running an A64 chip. I

installed Visual Studio 2003 and Visual Studio 2005 and as part of the

prereqs, both v1.1 and v2.0 of the framework respectively. I was able

to compile and run web applications, but after compiling and running a

windows application from either Visual Studio I received a "Application

failed to initialize properly." error everytime no matter what

application I compiled. My web apps worked, but my windows forms

didn't. Strange. This led me to believe it was a possible corrupted

framework problem.

So I uninstalled the v1.1 framework and tried reinstalling, but

everytime I got this message:

"NET Framework 1.1 Setup has ended prematurely"

This happens right at the very last step when trying to setup

System.EnterpriseServices

I've tried renaming mscoree.dll, removing all the .NET components,

running clean up tools, and everytime I run the 1.1 framework installation it won't install. It keeps failing at the very, very, very last step. :(

PLEASE, PLEASE help me here. I need to have these development environments

installed. They were installed before, but I had to uninstall them to

fix this problem, and now I can't even install the .NET frameworks.

I've never seen this issue before and I've been reading all over, and

every thing I'm told to do doesn't work. I just need a clear cut

solution to remove the .NET framework remnants and clean anew WITHOUT

having to reformat.

Thanks much Aaron, hopefully you can help me. :)

I reinstalled .NET 1.1 from my Windows XP CD and all is OK again now with no more error messages.

Thank you again.

Many thanks. The removal tool solved a very longstanding problem of being unable to install security update for .Net Framework 1.1.

Interestingly, the tool claimed to have failed. And Microsoft Update was not showing me .Net Framework 1.1 as an option. So the tool must have left something behind. But installing .Net framework manually, then its SP1 allowed Microsoft Update to show me the security update to 1.1SP1, which installed successfully (though did not actually require downloading, interestingly enough, indicating something else missed by the tool.

But the removal tool is great, even so!! Many thanks again Mr Stebner...

Hi Spock - I'm glad to hear that the cleanup tool was useful for you. This tool does not have an installer - it is just a zip file with the program inside of it. Therefore, you only need to delete the file to remove it from your system. There is not any uninstall program needed for this tool.

I tried to use your cleanup tool on my Win98SE system to remove any traces left from uninstall of .NET 1.0 and 1.1. The tool wouldn't work. It gave error message:

Error Starting Program

The CLEAN.EXE file is linked to missing SHELL32.DLL:SHGetFolderPathW

I tried running the program from the Windows Temp folder and Windows System folder where Shell32.dll is located, but still won't work. Any thoughts on what's wrong? Thanks.

re: Removal tool to fix .NET Framework install failures

astebner — Sat, 21 Jul 2007 00:06:43 GMT

Hi Mikey3 - This error means that the function ShGetFolderPath doesn't exist in the file shell32.dll on your system. The documentation for that function says that it requires at least version 5.0 of shell32.dll. I have written the code to delay load that DLL so that if a lower version were present, it should not cause any problems. However, there might be a bug in that code somewhere. Can you check on your system and see what version you have of shell32.dll on your system? Also, would it be possible for you to contact me at Aaron.Stebner (at) microsoft (dot) com so I could try to send you a private build to test out some options for fixing this issue? I haven't been able to find a system that I can reproduce this issue on so far.

re: Removal tool to fix .NET Framework install failures

astebner — Sat, 21 Jul 2007 00:32:18 GMT

Hi Mikey3 - I looked at the code for the cleanup tool a bit more and I found an issue that I introduced in the latest version that I posted to my file server that could explain the behavior you're seeing. Can you please try the updated version I just uploaded to http://astebner.sts.winisp.net/Tools/dotnetfx_cleanup_tool.zip and see if that fixes this issue? Please let me know how it goes for you.

re: Removal tool to fix .NET Framework install failures

Mikey3 — Sat, 21 Jul 2007 05:34:16 GMT

The new cleanup tool ran successfully, but also included an error message at the beginning of the log:

****ERROR**** GetProcAddress failed for 'SHGetFolderPath' with error code 127 - The specified procedure could not be found.

The shell32.dll is version 4.72.3812.600, and from FileSnoop it doesn't have the Export function "SHGetFolderPathW". Does the lack of that function affect any cleanup routines in your cleanup tool? Would anything be left on the PC because of it? I'm not planning to reinstall .NET Framework on this PC again because Microsoft doesn't offer any patches for it on Win98SE anymore - one less security problem to worry about. So, I can't tell you if a reinstall would work out well or not.

re: Removal tool to fix .NET Framework install failures

astebner — Mon, 23 Jul 2007 06:36:45 GMT

Hi Mikey3 - That error is expected if you have a version of shell32.dll less than 5.0.0.0. The cleanup tool tries to use shell32.dll to locate the Program Files directory on your computer, and if it fails to find the function that it needs, it will look up the location in the registry as a back-up. So, even with that error, the tool would have worked fine for you.

Hi Aaron. First let me add my thanks for this tool. I was in a hopeless mess trying to uninstall .NET to get rid of the dreadful 982366 upgrade problem. Your tool seems to have stopped the latter, and very nearly tidied up my installation. I just have one question - I still have Microsoft .NET Framework 1.1 Hotfix (KB886903) showing in Add Or Remove Programs. It will not uninstall ("The upgrade patch cannot be installed because the program to be upgraded may be missing . . ."), and it does not show up in Windows Install Cleanup. I really don't need .NET 1.1 at all any more, and I'd like to stop going round the endless install-uninstall loop and just get .NET2 installed and get on with my life, but it would be nice to get everything tidy and get this oddball hotfix out of the AORP list. Any suggestions?

re: Removal tool to fix .NET Framework install failures

astebner — Mon, 27 Aug 2007 20:26:12 GMT

Hi DaveMidgley - I'm glad that the cleanup tool was helpful for you. It sounds like there are a couple of additional registry entries left behind on your system that cause the KB886903 item to appear in Add/Remove Programs even though it has already been uninstalled. You can go and manually delete those - they will be located under HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall.

Also, if you don't mind, could you please report back the exact names of the keys/values you had to remove so that I can update the cleanup tool to remove those in the future as well?

Thank You.

The multi-page results log last line suggested the clean-up tool had failed..

Yet in my view, it seems to have helped me clear off Net.Framework 1.1 [not showing in the Add&Remove programs list]

The yellow MS caution crst is gone too! That was a reminder that Kb928366 ..

[Fatal execution error 90X7925de14

And KB928367..

process id = 0X3dc (988) 1.0 PK3 = 0X184 (388)

Were both always outstanding security updates that could not be loaded.

The cleanup tool did knock out MS Defender but I removed it and installed a fresh Defender.

When I rebooted after cleanup, only the big gold maple leaf backdrop was on the display... for a loooong time while the processor was busy at full tilt.

No desktop icons at all! I could see programs were loading in the lower tray though.

After a very long a nerveous wait. I hit {Start} and put the Compaq in [Standby].

Some minutes and I moved the mouse to start up and sign in and to my relief the whole screen load of icons were back.

So things seem to be running normally now. There may be a few more surprises waiting when I start different apps, but if unloading and reloading fresh does the trick, then all is well. Thank you again. = TG

PS The internet icon was missing from the tray... but that returned upon *Wake-up*

HI Aaron, I ran your tool on a W2K3 SP1 server and it failed to remove .net 1.1. I had to use your tool because it would not show up in Add/Remove programs, nor can I install updates to it. Your tool says it is deleting a number of reg keys and files, but it leaves the c:\WINDOWS\Microsoft.NET\Framework\v1.1.4322 path/files in tact. Further review of the log shows a line saying:

"Not adding product '.NET Framework 1.1' because the OS condition does not match".

Any ideas?

Hi Adambaum - As described at the top of this blog post, the .NET Framework cleanup tool will not allow you to remove any version of the .NET Framework that is installed as a part of the OS. The .NET Framework 1.1 is an OS component on Windows Server 2003, so that is why you are seeing this behavior.

If you need to repair the .NET Framework 1.1 on Windows Server 2003, you can try steps like the ones at http://blogs.msdn.com/astebner/archive/2005/06/21/431385.aspx.

Hopefully this helps.

I'm running Windows XP pro SP2 and I get the following error when I try to install .net 2.0

Help I have tried every single fix listed on this site and every place I could find on the internet.

error 25015.Failed to install assembly'C:\Windows\Microsoft.NET\Framework\v2.050727\System.Enterprise.Services.dll' because of system error: The system cannot find the path specified.

Thanks Robert

Hi Snouhtoau - In many cases where I've seen this error message in the past, the workaround at http://blogs.msdn.com/astebner/archive/2006/11/25/disabling-services-with-msconfig-to-work-around-setup-failures.aspx has helped. I'd suggest trying that if you haven't already.

If that doesn't help, and if running the cleanup tool listed at the top of this blog post also doesn't help, then I'd suggest posting a question on the MSDN Forums at http://forums.microsoft.com to see if someone there can help suggest any other workarounds.

Please help.

I tried using the tool and have uninstalled the tool. Can't confirm that but the tool say so.

Then I ran the Windows Update which highlights to install .Net 1.1, 2.0 and 3 versions to be installed. When I tried installing the .Net 1.1 version, after a while error came Unable to install the frmaework.

I tried downloading and installing the .Net 1.1 framwork, I got 1935 error.

please help

Hi Pravesh - I'm sorry for the hassle this issue is causing for you. You can use the steps listed at http://blogs.msdn.com/astebner/archive/2005/03/29/403575.aspx to make the .NET Framework 1.1 setup create a verbose log. Then you can zip and send me the log at Aaron.Stebner (at) microsoft (dot) com and I can try to take a look and see if I can figure anything out about the root cause of this 1935 error.

Have experienced this error on a Win XP Pro box. Have used the Cleanup tool with no results. I am going to go through the procedures you mentioned on http://blogs.msdn.com/astebner/archive/2005/04/16/408856.aspx but was wondering if you had specific success stories concerning THIS error with THIS file. I had not seen any in going through this forum...

Also - you say that we are allowed a free support call for this kind of issue - yet there is nowehere on the support site that I can find anything dealing with .NET Framework installations or .NET FW 2.0, and the only contact options are pay per use.

Thanks!

re: Removal tool to fix .NET Framework install failures

astebner — Fri, 01 Feb 2008 02:11:42 GMT

Hi Cnsrvative - Do you have the full text of the error message that you're running into in this scenario? Error 25015 is a catch-all for any type of error that the installer doesn't specifically recognize (in coding terms, it is the default case at the end of a big switch statement), so there are a lot of possible causes. Usually, error code 25015 will be followed by some more specific information about the cause of the error.

The name of the file being installed doesn't usually help narrow down the cause, but since it mentions System.EnterpriseServices.dll in this case, you may want to see if either of these workarounds helps for you:

http://blogs.msdn.com/astebner/archive/2006/01/08/510677.aspx

http://blogs.msdn.com/astebner/archive/2006/11/25/disabling-services-with-msconfig-to-work-around-setup-failures.aspx

If you've already run the cleanup tool, there's no need to also try the steps in that other blog post. Those steps are the same as the ones run behind the scenes by the cleanup tool.

Regarding the support question, my understanding is that you can use the Developer Tools support option like you would for Visual Studio, and that installation issues do not require payment. I'm not sure if there have been any policy changes since I heard about that though.

Hopefully this helps.

This tool has just saved me from going out of my mind. I tried to install SP3 for Framework 2.0 and it failed, when I tried to delete it from my system I couldn't, when I tried to re-install Framework 2.00 kept getting the same error message. I got no sense at all fro, Mircrosoft Help & Support. Then I found this tool, and everything fell into place.

Thank you very much for your expertise.

Thank You! Thank You! Thank You!

The path that has led to this point is unbelievable. All I wanted to do was update the video drivers on my ATI 8500DV card on my Win2K box. The boxed CDROM drivers installed fine, but the updated drivers bombed, complaining about missing mscoree.dll. Of course it was missing, I had never knowingly put dotnet on my machine (nor did I want to!). So I got a copy of 1.1, but the installation failed repeatedly with "Microsoft .NET Framework (English) v1.0.3705 -- Error 1904.Module C:\WINNT\system32\mscoree.dll failed to register. HRESULT -2146232576"

Anyway, I was about to give up and re-format my drive (and spend a week or more putting everything back), when I came across your blog.

IT WORKS! Thanks again. -Alan (a reluctant and resentful dotnet user)

Helo all,

i got big problem. During migration of servers i have uninstall .net framwork 3 sp1 from server. Uninstall was successfull.

Now i need to install some application which need .net framework 3 but i cant install it. If i try to install verson 3 it said that there is already installed newer version and if i try with 3 sp1 i get error on the begining of the installation. Even 3.5 doesnt help.

I cant uninstall or install. In one word i am stuck and cant do anything.

Try your tool and didnt help me. It clean system but cant install it. Is there any other way to tell system that it isnt install yet?

One way i manage to install app is to install new .net framework 3.5 sp1 beta but that also upgrade version .net 2 with sp2. Can i get installation for only .net framework 3 sp2?

Thanks for any comments or tips.

Peter

I have tried EVERYTHING to be able to Install .NET Framework 2.0. Uninstall / reinstall, clean out all versions of .NET, etc etc etc you get the idea.

I am still getting the error System.EnterpriseServices.dll can not be found when installing.

I've checked the directory and before the install the file doesn't exist. During the install it creates the file, and after it fails and I hit finish it deletes it again.

I disabled McAfee as well. Any more ideas here?

Please email me for faster communication. I am in a corporate environment and even our IT people are stuck and I need this fixed ASAP.

re: Removal tool to fix .NET Framework install failures

astebner — Thu, 22 May 2008 22:17:10 GMT

Hi Vaximily - I'm sorry for the hassles that this issue is causing for you. It sounds like you've tried most of the steps that I know of for troubleshooting .NET Framework installation issues. There are a couple of other things that are specific to issues with System.EnterpriseServices.dll that you may want to try as well:

http://blogs.msdn.com/astebner/archive/2005/07/27/444085.aspx

http://blogs.msdn.com/astebner/archive/2005/07/24/442747.aspx

http://blogs.msdn.com/astebner/archive/2006/01/08/510677.aspx

Also, if you haven't already tried it, you may want to try disabling services with MSConfig as well using the steps at http://blogs.msdn.com/astebner/archive/2006/11/25/disabling-services-with-msconfig-to-work-around-setup-failures.aspx.

If none of the above work, then I think you will need to contact Microsoft Technical Support for more in-depth troubleshooting assistance. There is contact information at http://support.microsoft.com and you should be entitled to a free support case for setup-related issues such as this.

Hopefully this helps.

re: Removal tool to fix .NET Framework install failures

vaximily — Thu, 22 May 2008 23:09:16 GMT

Error 25015. Failed to install Assembly 'C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.EnterpriseServices.dll' because of the system error: The system cannot find the path specified.

Any more help before I throw this thing in a box and send it back to Dell?

re: Removal tool to fix .NET Framework install failures

astebner — Thu, 22 May 2008 23:21:29 GMT

Hi Vaximily - In the past, I've seen cases where this has been caused by a virus on the system and by programs like Windows Defender being too aggressive in what they are protecting. You may want to check and see if you have Windows Defender running in the background in addition to McAfee just in case.

If that doesn't help, then I don't know of any additional suggestions to try. However, before you return your computer, I would strongly suggest contacting Microsoft Technical Support as I suggested previously. They should be able to help you debug this further directly on your system and will hopefully help narrow down the cause and help you fix this. They have worked on several cases in the past that resulted in this same error message that I am aware of and have been able to successfully fix all of them so far. The hard part here is that there are a lot of possible root causes for this type of error and it typically takes some direct debugging to walk through some of the diagnostics.

I'm very sorry for the hassle that this is causing for you.

re: Removal tool to fix .NET Framework install failures

vaximily — Thu, 22 May 2008 23:28:14 GMT

Do you know the typical turn around time for something like that would be? My company modifies all sorts of security setings to lock down our systems pretty heavily, so at this point it seems easier to just have them send me a new laptop and I'll send this one back to them so they can format it or return it to Dell.

I don't think there's a 'virus' as our network is locked down pretty solidly --- unless you count their monitoring junkware as a virus!! :)

re: Removal tool to fix .NET Framework install failures

astebner — Thu, 22 May 2008 23:49:03 GMT

Hi Vaximily - The typical turnaround time is a day or two. If you'd like, you can contact me via email and I can help you get a case created - Aaron.Stebner (at) microsoft (dot) com. If your company can easily give you a new laptop and reformat the current one, it may not be worth that trouble though. Let me know what you'd prefer to do.

Also this is windows server 2003 r2 sp2 x64.

re: Removal tool to fix .NET Framework install failures

astebner — Mon, 26 May 2008 01:31:07 GMT

Hi Beemf - Since you're running a 64-bit OS, could you also check and see if you have a v3.0 key at HKEY_LOCAL_MACHINE\WOW6432Node\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0?

If you're getting an error saying a later version of the .NET Framework 3.0 is already installed, that typically means there is something incorrect in the registry somewhere.

re: Removal tool to fix .NET Framework install failures

Beemf — Tue, 27 May 2008 08:58:02 GMT

Hi,

I check under LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\NET Framework Setup\NDP\v3.0 and v3.0 was there. I just delete v3.0 folder and the installation of .net framework 3 sp1 was successful.

Is that ok? Just delete all content under v3. I was doing that on copy of virtual server and dont want to damage production server.

Thanks for all the help Astebner.

re: Removal tool to fix .NET Framework install failures

astebner — Tue, 27 May 2008 21:33:15 GMT

Hi Beemf - .NET Framework 3.0 and 3.5 setup use registry values in locations like that to determine if a newer version of the product is already on the system, so it is probably OK to remove those values in order to unblock installation if you are getting that error and you are sure you don't already have a newer version installed.

Just to be sure though, can you list exactly what you have in your registry at that location so I can take a quick look?

Oh dear me, I think ive messed up using this thing.

I couldnt install framework 3.5, so i used your tool and wiped all framework installation of my pc.

Since im on vista premium 64x its not so happy about not having framework 3.0 installed.

The big problem is when i try to install framework 3.0, it gives me an error saying I need to "activate or deactivate windows-functions" in the controlpanel to install or configure microsoft.net framework 3.0 x 64. (basically translated from danish to english)

The real problem is that there doesnt seem to be anything to activate or deactivate in "windows-functions" under programms and functions, where you are supposed to be able to turn on and off windows-functions such as allowing the framework 3.0 x 64 to be installed/configured :S

re: Removal tool to fix .NET Framework install failures

astebner — Tue, 09 Dec 2008 21:49:55 GMT

Hi Davegrohl - The .NET Framework 2.0 and 3.0 are installed as OS components on Windows Vista, so the .NET Framework cleanup tool on my blog will not even attempt to remove those. Normally, the .NET Framework 3.0 will appear in the Windows Features control panel along with other OS components, and it will allow you to activate or deactivate it.

However, in your case, you don't have anything listed in that dialog. It sounds to me like there is some kind of bug in the OS on your system that is preventing it from listing the OS components you have installed. I'm not sure how your system got into that state or how to resolve this type of issue.

I did a web search and there appear to be quite a few people who have run into this though. Here are a couple of links that might help:

http://support.microsoft.com/kb/931712

http://blogs.msdn.com/astebner/archive/2008/07/28/8786504.aspx

If none of these help, you may need to try to repair/re-install Windows Vista on your system.

After running your tool several times I was not able to install .net 1 sp3 and .net 1.1 sp1, but all the other .net packages excluding 3.5 sp1. I saw your other article about 1603, but I guess I need to clear this problem first. I am running XP Pro SP3.

Aaron, I neglected to mention that I am running XP SP3 and I recently did a repair installation of Windows and had .NET framework issues afterward(the computer said they weren't installed, installation said they were). I ran your tool and am now in the process of reinstalling.

I appreciate any help,

Keith

Hi Kclewis - The System.TypeLoadException that you are encountering typically means that there are some old .NET Framework 3.0 bits left behind somewhere on your system that are interfering with .NET Framework 3.0 setup. I'd suggest trying to use the steps listed at http://blogs.msdn.com/astebner/archive/2008/03/07/8108332.aspx to remove all versions of the .NET Framework from your system, then proceed to install the .NET Framework 3.5 SP1 (this will install 2.0 SP2 and 3.0 SP2 for you behind the scenes).

Unable to run the tool number of times on XP64 OS

Hi ,

I have to perform testing of installing and uinstalling the software repeated on XP64 os. As a part of Install and Uninstall, i have to repeatedly install.net and uninstall the .net. I am using clean up utility tool for the same.

I have seen that After performing uninstallation of .net3.5 and .net3.0 for some number of times the the tool gets hung or goes into infinite loop.

I have seen that this is because there is a HOT fix from Microsoft that cannot be uninstalled.The Hot Fix no is :KB953595.

Hi Vvkalkundri - First of all, the cleanup tool is not designed as a replacement for the standard .NET Framework uninstall process. I would suggest automating the standard uninstall for your test scenarios so you will more closely match what a customer will actually do on their system. I have posted other items on my blog about how to automate the install and uninstall of various versions of the .NET Framework - you should be able to search my blog archive to find them.

That being said, I don't know of any reason why the cleanup tool would hang. Do you have log files from the cleanup tool when it is hanging that you could post on a file server so I can take a look at?

I have windows vista installed on my laptop ..But the first time windows update tried to install some new updates it said something about an error.. everyday it tries to install the new updates that have to do with the net framework and it says that I have to go to the control panel and unistall the net framework and then activate or disactivate some windows' functions and try to install the framework again..

I have tried almost everything but the probleme doesn't go away..

can you tell me a way to fix it ??

I asked a computer technician and he told me that we have to unistall windows nad install it from the beginning.. Isn't there another way???

Hi Soultmich - I'm sorry for the hassles that this issue is causing for you. I'd first suggest trying to use the steps listed at http://blogs.msdn.com/astebner/archive/2009/10/23/9912209.aspx to see if they will help resolve this .NET Framework update installation problem.

If that doesn't help, please use the tool described at http://blogs.msdn.com/astebner/archive/2007/11/21/6458047.aspx to gather your .NET Framework setup log files, then upload them to a file server of your choice (such as http://skydrive.live.com), then reply back here with a link that I can use to download the logs so I can take a further look and see if I can figure anything out about what is causing this problem on your system.

I tried the cleanup tool, unfortunately I'm still getting an error code. The problem appears to be an empty folder that is restricted on my computer. Funny thing is, I've never created a logon other than computer owner, so nothing should be restricted. Is there any kind of work around to install .NET framework?

Thanks, Steve

Hi Happyharrell - I'm sorry for the hassles that this .NET Framework setup issue is causing for you. What exact version of the .NET Framework are you trying to install, and what version of Windows is it on? Could you please use the tool described at http://blogs.msdn.com/astebner/archive/2007/11/21/6458047.aspx to gather your .NET Framework setup log files, upload them to a file server of your choice (such as http://skydrive.live.com), then reply back here with a link that I can use to download the logs so I can take a further look and see if I can figure anything out about what is causing this problem on your system?
