There is a known issue with the QFE we released in December 2003 to include the .NET Framework 1.1 for XP Embedded. It creates 2 shortcuts on the start menu that are in Japanese (which may show up as square boxes if you do not have the full set of Japanese fonts and settings included in your embedded image). This will be fixed in the upcoming XP Embedded SP2 release, but in the meantime you can work around this issue by doing the following prior to building your XP Embedded image:
If you have built your image but not yet had FBA run on it, you can go to the \Windows\Inf directory and locate the file netfxocm.inf and make the same change described above.
I posted this item a while back in the newsgroups but I wanted to put it in my blog also because I think it may have gotten a little buried amongst all the posts there. We have seen many reports of bugs related to calling into performance counter APIs on XP Embedded. These have shown up most commonly when using the System.Diagnostic.Process class in the .NET Framework but can also be seen when using certain native APIs. The underlying issue is a registry key that is incorrectly populated when creating an XP Embedded image. This issue will be fixed in the upcoming XP Embedded SP2 release, but I also wanted to provide a couple of workarounds that can be applied in the meantime.
If you have not yet built your XP Embedded runtime, you can do the following:
If you have already built your runtime, you can delete the registry key named HKLM\Software\Microsoft\Windows NT\CurrentVersion\Perflib\009\ and then reboot your machine to fix this issue.
Hey all, thanks to your posted comments, I realized that the exclusion list I posted here originally was not in the correct syntax for the InCtrl5 tool to understand it.
There is not a way to exclude files in the InCtrl5 tool, so you will need to look at the exclusion list at http://www.winisp.net/astebner/bin/inctrl5_exclusion.txt and manually exclude them after running the tool for the setup you are trying to model.
For registry keys, I have created a new file in the correct format at http://www.winisp.net/astebner/bin/inctrl5_registry.txt. You can download this file, rename it to InCtrl5.ini, and copy it to \Program Files\InCtrl5 on the machine that you have installed InCtrl5. This will cause the tool to ignore this set of registry keys/values when analyzing a setup.
Hope this helps....
Hey all, I'm happy to report that we figured out the root cause of the really strange rollback behavior we saw in the .NET Framework setup (described in a post earlier this week) and I wanted to pass on what we found in case any of you hit this issue with a Windows Installer-based setup in the future. Here is a rough outline of the issue and the underlying problem:
The only thing we are not sure about is why the RBS file was orphaned in the registry and on the user's machine to begin with, so we'll have to keep digging into that if we get any additional repro machines and see if we can figure it out. We are going to look into making the next version of Windows Installer smarter about which RBS files it will run when it is removing backup files to try to help avoid this scenario in the future, but in the meantime if you encounter this behavior in any of your scenarios, start by taking a look at that registry value and see if there is any orphaned data that may be causing your setup to rollback.
Hope this helps......
I found this really cool article this morning about a project at Cornell University where they're building an unmanned aircraft with onboard embedded control systems that are running XP Embedded - check it out at http://research.microsoft.com/displayArticle.aspx?id=685
My colleague, former manager and friend Michele Coady is currently an international test lead on the Visual Studio and .NET Framework localization team. She sent me a really interesting link today that I wanted to pass on for anyone who may be writing world-ready applications. Colors have different meanings and cultural implications depending on the audience, and it is very important to keep the connotations in mind when writing applications for worldwide audiences. Anyone writing worldwide applications should take a look at this article, and even if you're not, this is an interesting read - http://www.colorconnection.xerox.com/wwwco578/html/en/tips/international.html
I saw a very odd rollback behavior in the .NET Framework setup yesterday that I thought I should post in case anyone else runs into something similar. This was the 2nd time I saw it, but the first time in a scenario from a non-Microsoft internal machine. When it first happened I had written it off as a one-off caused by daily builds of the OS, the .NET Framework or something like that. But apparently it is possible to get the machine into this state through released products (possibly beta bits, but still valid in my opinion)
Essentially what happened was the .NET Framework setup proceeded all of the way through installation and then initiated a full rollback. I couldn't find any evidence in the verbose MSI log file that any kind of error had triggered the rollback, and the last section of the log told me that the return code was 0 and that the .NET Framework installation completed successfully. I had to use filemon and regmon (from http://www.sysinternals.com) to diagnose that there was a file in the folder c:\config.msi named *.rbs that was being executed, and then finally I traced it back to the following registry value on the machine:
I wasn't able to determine how that value got set, and searching for information about this registry hive in msi.chm and on the internet didn't yield any conclusive information. The closest I came to a possible explanation is in the section named Active (Incomplete) Installations at http://www.microsoft.com/resources/documentation/WindowsServ/2003/all/techref/en-us/Default.asp?url=/resources/documentation/windowsServ/2003/all/techref/en-us/msizap_remarks.asp
What I think may have happened is some other Windows Installer setup (more than likely the .NET Framework itself) got orphaned before it completed, and then this script was left behind in the registry and inadvertantly got launched by future installations. Normally when a Windows Installer setup gets orphaned and you try to run another MSI, it will say that an installation is currently in progress and is suspended and asks if you want to rollback before you continue with the new setup, but for whatever reason we didn't see that in these 2 instances. I'm still hoping to get a more thorough explanation from the Windows Installer team about what is really going on here, and I'll post my findings back here.....
Hey, I'm slowly but surely getting other folks on my team to create blogs. Neil Marlowe is a program manager who I work closely with - some of you may have met him and attended one of his talks at Embedded DevCon. His primary focus is the Embedded Enabling Features (EEFs) like me, plus he's got some expertise on embedded security and servicing scenarios. Take a look at his blog at http://blogs.msdn.com/neilmarlowe/ if you have a chance, he's planning to post some good how-to documentation in the near future about using the ICF utility to protect embedded devices....
Hey all, as I promised a while back, I wanted to walk through some examples of how I approach reverse engineering a setup package to learn how it works, make any necessary changes, figure out command line switches, etc. I apologize for not posting anything in a while, I was spending some time with my family who was in town from Texas and then I managed to get sick right after they left. But I'm back now :-)
I'm going to start with a relatively straight-forward reverse engineering example - the .NET Framework 1.1 package. I chose this first because that setup is very simple - no setup data files, no configurable setup UI options, etc. Yet it is complicated enough to be interesting and it is a setup that a lot of people want to include in their setup packages and/or have had issues trying to install. I'm going to try to approach this from the perspective of someone who is familiar with different types of setup technologies in a broad sense, but who has not yet seen this particular setup before (I may get a little off track on this part because I'm so familiar with this setup from my previous work, but I'll try.....)
Step 1 - figure out what packaging technology is being used
When I download the .NET Framework 1.1 I see that it is a single EXE named dotnetfx.exe. When I double-click on it, setup asks me if I want to install and when I say Yes it proceeds to extract files to the %temp% folder on my machine. Then a EULA appears. When I go to %temp% after the EULA appears, I see a folder named ixp000.tmp. This tells me that the package in question is an IExpress self-extracting EXE. Since I know it is IExpress, I can now use some well-known IExpress command lines to extract the package to a folder of my choosing. I will run dotnetfx.exe /t:c:\aaron /c to create a folder named c:\aaron on my machine and unpack the .NET Framework files to this folder. The /t flag specifies the folder to extract to, and the /c flag specifies that I want to extract the files only and not run the setup after extraction.
Side note for setup developers - I found some IExpress docs on the web here, and you can also find iexpress.exe in %windir%\system32 on an XP Professional machine. It is a useful tool for packaging up multiple files into a single package but it is also a fairly old technology and has some limitations that may not make it practical to use, depending on your scenario.
Step 2 - figure out what setup/installation technology is being used
Now that I have extracted the files, I will go to the c:\aaron folder that I created above.
Step 3 - figure out the basics of how the setup works
After I look at all of this, I go ahead and step through the UI and install the .NET Framework 1.1, and then re-open the log file dotnetfx.log. I see that it lists the command line that is passed to the MSIInstallProduct function - and I know that this is an API call for an application to install a product using Windows Installer. Then I see a return code for that API call - fortunately it is 0 in this case to tell me that the .NET Framework 1.1 installed correctly. Then I see another call to StopDarwinService, so this install.exe application is stopping the Windows Installer service again after installation is complete - kind of strange.
Step 4 - figure out details about how the setup works
Now that I have a basic understanding of how the .NET Framework 1.1 setup works, I'm going to use my Windows Installer expertise to dig a little deeper. The first thing I will do is install Orca, then right-click on netfx.msi and choose Edit with Orca to view the contents of the MSI. There is a ton of data to wade through in an MSI and it is overwhelming at first, so I will only look at a few key things here:
There are many more things that we could look at in an MSI, but the above are good starting points. Often for other setups you will see items in tables that will lead you on trails through other tables. Most commonly, if there are launch conditions that depend on the existence of other applications, you will be led to the AppSearch table to figure out exactly what file or registry data the setup is looking for when deciding whether or not to block.
Step 5 - install with verbose logging and look at the MSI log file
Reading an MSI log file is more of an art than a science but can often be useful when reverse engineering a setup. For the .NET Framework 1.1, we know that because it is an MSI we can set the verbose logging flags before running setup - HKLM\Software\Policies\Microsoft\Windows\Installer, Debug (REG_DWORD = 7) and Logging (REG_SZ = voicewarmup!). These will give us a verbose log named msi*.log in %temp% where * is a randomly generated set of characters.
I also noticed when running install.exe /? it says that if you pass a /l flag it will generate netfx.log in %temp%. Since I also noticed that the log created by running install.exe was named dotnetfx.log and not netfx.log, I might be curious what the difference is and run install.exe /l from c:\aaron to see what it does. When I install this way I see that the resulting file %temp%\netfx.log is essentially the equivalent of a Windows Installer verbose log file without needing those registry keys to be set. So now I can take a look at netfx.log (or msi*.log if I choose) and view the step-by-step process of this setup.
With that, the process of reverse engineering the .NET Framework 1.1 setup is done for the common cases. There is of course more detail that may be needed depending on your scenarios, but much of that will require more in-depth analysis of the MSI tables and/or the verbose MSI log files. I will leave that for a later lesson.
Side note for the curious - the reason that the .NET Framework 1.1 setup stops the Windows Installer service is because Windows Installer uses pieces of the .NET Framework to install assemblies to the GAC (the MSIAssembly and MSIAssemblyName tables in the MSI) in Windows Installer 2.0 and higher. This creates a classic chicken-n-egg problem - Windows Installer is going to install the .NET Framework but Windows Installer needs the .NET Framework in order to do so. Because of that, Windows Installer has some special logic to bootstrap the part of the .NET Framework it needs to install assemblies, but since Windows Installer is run as a service, it could already be running from a previous setup and we want to stop the service to unload any older versions of the .NET Framework from memory so that the most recent version will be used.
I hope this post is at least a little bit useful to give some insight into how I approach the process of taking apart a setup and figuring out how it works. I will post more later with a more complicated example of a setup that uses information from data files, etc. Let me know via comments or emails if you have any questions about any of the above.....
My colleague Alaks Sevugan created a pretty comprehensive list of file and registry exclusions that can be used with the InCtrl5 tool to eliminate noise when trying to convert an application installer to an XP Embedded component. Click on the link below to download it and try it out....
A lot of you probably know this already, but I wanted to list these steps for the record. If you are debugging an application issue or just want to make a quick change to your image and redeploy it without needing to open Target Designer and rebuilding your image, you can do the following:
After following these steps, you can deploy your image and any registry changes you made will take effect in your embedded OS. Hope this helps.....
While searching for orca.msi earlier today to try to determine whether or not it is available outside of the Platform SDK, I stumbled upon a really cool list of MSI tips, tricks and tools. There is one tool in there that rates the complexity of an MSI, I'm going to have to run that against the Visual Studio MSI when I have some time tomorrow, I'm really curious to know what that will come back as. I would think it has to be more complex than the Office setup package :-)
As a side note - I've gotten a couple of mails from internal folks about posting orca.msi and I'm not quite sure if it is intended to be posted outside of the Platform SDK so I may have to take it down. I can't think of a reason why we wouldn't make such a critical MSI debugging tool harder to obtain than it needs to be so hopefully I can convince the right people that we should be making it available for direct download. But we'll see.....
Stephane Rodriguez posted an interesting comment that I hadn't thought of - it isn't the easiest thing in the world to download Orca. You have to go through the Platform SDK web-based installer tool and also install a bunch of pieces of the core SDK to get orca.msi which lets you install Orca. I have a copy of it that I downloaded and posted at http://cid-27e6a35d1a492af7.skydrive.live.com/self.aspx/Blog%5E_Tools/orca.zip for easier access. I hope this makes things easier for you as you debug your setup packages.

While I was on the Visual Studio and .NET Framework setup team, a colleague and I took a trip to visit 2 universities - MIT and USC - to validate the plans and designs we were working on to add support to our setup UI to generate transforms for Active Directory deployment for the Whidbey version. During this trip, I was struck by the level of MSI knowledge that the system administrators at both of these schools possess, and also by how willing they were to reverse engineer setups to do any/all of the following:
The universities that we visited and many others that I've talked to who are in charge of software deployment simply need to roll out standard OS images with specific applications, and too few app developers understand the implications of their setup development decisions on things like admin deployment.
Then, when I joined the Windows Embedded team, I found a common theme among embedded customers - they need to install drivers and applications onto their embedded images, but they do not ship components that can be used by Target Designer and the embedded tools. This leaves the following options
It really struck me to think about the similarities in the problem spaces between the 2 teams that I have worked on at Microsoft. It also got me thinking because I have been working with and studying setup technologies for the 5 years I've been working at Microsoft, and over that time I've learned to think the way a setup developer thinks so that I can take apart a setup and figure out what it does. However, despite all of this experience, I still haven't seen any 2 setups that behave in exactly the same way.
I have come up with some tricks that can be useful to take apart a setup and figure out what it does, debug issues, and reassemble it in new ways. I'll list out some of the MSI-specific tips and tricks I've seen and used, and then some more general ideas:
Reverse Engineering MSI-based Setups
Random Tricks for Packaging and Reverse Engineering
It seems like I have more tricks that I've used but I can't seem to remember them all right now. I'm getting tired tonight, but I think tomorrow I'll take Visual Studio and .NET Framework setup packages and walk through some of the inner workings and show how I use some of the above tricks.
I have no idea if anyone but me is really interested in the theories and technologies behind setup creation, but if you made it this far and have comments/suggestions/questions/etc please send me an email or post a comment. Thanks!
Hey all, it looks like the Visual Studio setup team has heard all of the feedback because they have posted manual installation instructions for the Express SKUs. Here is a compilation of all of the useful links:
Manual Install Instructions
Direct Download Links
If you are on a very slow connection or have a pay-by-the-megabyte connection or something like that, you can use this link to order CDs - http://lab.msdn.microsoft.com/vs2005/get/order/. You will only be charged the cost of manufacturing the CDs and shipping them to you.
The setup team would like to ask you to please try the downloader application before linking to the packages directly because this is a beta and they are looking for all of the feedback and bug reports they can get for this new feature. Please report any issues you find while installing or using the products at the product feedback site - http://lab.msdn.microsoft.com/productfeedback
If you download the packages, you can use the instructions I posted at http://blogs.msdn.com/astebner/archive/2004/07/05/173639.aspx to create an installable layout and optionally burn it to a CD. These steps will give you the same layout of files as the CDs that you can order from the link above.
Let me know if you have any comments or questions, hope this helps....
A couple of folks who attended the session and/or the hands-on lab I presented at Embedded DevCon last week regarding remote debugging had specific questions about whether or not the strategies I presented would work on a minlogon image.
I followed the steps in Mike Hall's debugging tip sheet at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnembedded/html/embedded06072004.asp?frame=true using a minlogon image and found that native remote debugging worked fine for me on this configuration.
So I encourage those of you who are interested to try it out and send me email or post feedback here if you run into any issues or have any questions.
There is a new version of DUAScriptGen now available at http://www.winisp.net/scrat/DUAScriptGen/DUAScriptGen.zip
It contains the following fixes:
As always, please let Mike Hall and/or me know if you see any bugs or have any feature suggestions. Thanks!
Hey all, one of the feedback forms from the hands-on lab I presented about remote debugging indicated that you'd like to hear more information about how to use the Microsoft Loopback Adapter that I used to mimic a LAN connection within the local machine to connect the development OS to the virtual machine. Here are the steps I used to setup the loopback adapter. I am going to see about creating a more formal tip article for this and post it somewhere on MSDN's embedded site also. Please send me any feedback about whether or not this set of steps ends up working for you.....
Installing Microsoft Loopback Adapter
Now that you have installed the Microsoft Loopback Adapter, you need to configure an IP address for it.
Configuring Microsoft Loopback Adapter
Now you can disable your current LAN connection and enable your Microsoft Loopback Adapter connection by right-clicking on each connection in the Network Connections control panel and choosing Enable or Disable.
Earlier, I posted some random thoughts and notes that I took at the first XP Embedded Ask the Experts session at last week's DevCon (see the post at http://blogs.msdn.com/astebner/archive/2004/06/30/170582.aspx). I also want to post some stuff that I wrote down from the 2nd Ask the Experts session (last Thursday at lunch). I'm sorry it has taken me this long to post this stuff.....I'm going to be working with my team in the next couple of weeks to come up with plans to address all the great feedback and ideas we heard last week at DevCon and I'm really excited to get moving on some of this stuff....
I'll keep everyone posted on progress in these areas as we make it.....thanks again to everyone who attended DevCon and provided us with your valuable input into what we're doing well and more importantly where we're not doing so well.....
I've seen numerous issues and comments related to using the customized download manager to control downloads of the Visual Studio Express SKUs and their prerequisites and optional addins such as SQL and MSDN. Here are a couple of options that you can use to directly download the packages and then run from your local machine to install the beta bits:
If you want, you can also assemble the equivalent of a CD layout on your local hard drive. To do this, use these steps:
If anyone tries this and hits any problems please email me or drop me a comment and I'll help wherever I can. Thanks!

My former group (Visual Studio and .NET Framework) has signed off on the beta1 bits for the new 8.0/2.0 versions, codenamed Whidbey. One of the last big setup projects I worked on was the download logic for the Express SKUs - these are replacements for the “standard” versions of Visual Basic, C#, J#, C++, along with an additional SKU named Visual Web Developer (think of VID 6.0 with all the cool stuff that goes with ASP.NET and without all of the annoyances of VID).
The coolest thing of all is that you can use the downloader to get yourself a free copy of any of the 5 beta express SKUs and you don't even officially have to be a part of the Visual Studio beta program. Just go to the site at http://lab.msdn.microsoft.com/express/ and choose the version(s) you want, and off you go.
I'd be really curious to hear what you think about the experience of downloading and installing Visual Studio directly from the web, so if you try it, drop me a comment. If you're not a part of the Whidbey beta program and you have any bugs to report and/or suggestions for ways to make the experience better I will fill out a bug report for you so your voice will be heard by the Visual Studio team.....
It took me way too long to do this, but I've now got a link to Jon Fincher's blog on my site. He is a Program Manager that works on XP Embedded along with myself and others, he's been in the group for a very long time and has a ton of experience, tips and tricks to offer. Plus he's got a very good sense of humor so his posts are more fun to read than mine are!
He gave some really cool demos and presentations at Embedded DevCon about the new features that will be coming up when XP Embedded SP2 is released later this year. I encourage all of you to take a look at his blog when you have a chance.....
The second part of Mike Hall's “Going Virtual” article about using Virtual PC to setup an XP Embedded image and perform remote debugging using Visual Studio .NET 2003 has been posted on the Get Embedded site, take a look by clicking here.
For those of you who attended Embedded DevCon this past week in San Diego, some of this will look familiar - I helped Mike figure out some of the Visual Studio debugging details, especially the nuances needed to get things working on XP SP2 with the new firewall features, and I presented some of these techniques in my remote debugging talk on Thursday the 1st.
I'm going to work with Mike to publish a similar article describing how to configure machines for managed remote debugging using the techniques described in my debugging talk. The steps required for that are more involved but can prove to be very useful when readying your apps for an embedded device. So stay tuned for that.....
Well, I've been here in San Diego since Monday and attended the first 2 days of the Embedded DevCon 2004 show. I sometimes forget how tiring it can be just to be on your feet all day since I'm used to spending most of my work day sitting in front of a computer. But it has been amazing to get a chance to meet so many customers and talk about the wide variety of directions people are going with the embedded tools and different development and deployment strategies.
So far, I haven't presented (since I got “lucky” enough to have both of my talks on the last day of the show), so instead I have been acting as a proctor for the hands-on labs other folks in my group have been presenting. I also went to a lunchtime Q&A session called “ask the experts” today, though I don't know that I can really consider myself anywhere near an expert given my relatively short time on the embedded team and the wide range of issues that our customers see every day. Overall though, this was a great chance for me to see some of the specific pain points and give me some ideas to take back to Redmond when I head back on Friday.
Here is a list of the things I took notes on during the Wednesday “ask the experts” session that I specifically want to research and come up with plans for addressing:
This afternoon I went to my colleague Nandini's talk about First Boot Agent (FBA). I thought she did a great job of presenting her material and fielding the questions at the end of the session, I only hope that my talks tomorrow go half as well as hers. What struck me about the questions was the amount of interest in resealing and cloning. These are aspects of XP Embedded that I haven't explored very much yet in my time on the team and I'm going to make a point to get a greater understanding of how these work and where the problems are in our current cloning support.
Wow, I've let the time get away from me while typing out this stuff and I still need to practice my presentations one more time before I fall asleep so I'm going to sign off for now.
Hey all, I have been working to finish up the presentations, demo applications and lab machines for the presentations that I'll be giving at Embedded DevCon next week. Both of my presentations are on Thursday the 1st, so I'll be spending time meeting folks, answering questions and seeking better understanding of what we're currently doing well and where we can improve in the end-to-end Windows XP Embedded user experience.
Currently it appears you can only access the full contents of my presentation if you are officially registered for the conference. You can see the abstracts by going to http://www.windowsembeddeddevcon.com/tech_sessions.asp and http://www.windowsembeddeddevcon.com/tech_hands_on.asp and navigating to the “Track: Application Development” sections. I'll be presenting XPEA Hands-on Lab 1 (application development for XP Embedded) and XPEA-300 (remote debugging on XP Embedded). I'm really excited to share some of the tips and tricks I've learned during my time on the Visual Studio and .NET Framework team and combine that knowledge with resources specific to XP Embedded to enable easier and faster application development on this platform.
I hope to see you all at the conference!
I will be posting more later this week about some ideas around application repackaging, so stay tuned for that if you're looking here for setup technology discussions. The really interesting thing is that I've found that application repackaging is something that affects the embedded problem space just like it does for the desktop OS problem space, just with some different implications. In the next couple of days when I'm less tired I'll type up more and see where my thought processes go.....
