More detailed steps to fix .NET Framework install errors that ask for tmpXXXX.tmp

  • Comments 24

I previously described a set of steps in this blog post that can be used to manually remove the .NET Framework and reinstall it if you receive an error message stating that setup is unable to find the file tmpXXXX.tmp when attempting to install a .NET Framework service pack or hotfix.   However, I've heard from a couple of customers over the past few weeks who still received errors related to tmpXXXX.tmp after performing the cleanup steps in that blog post.  As a result, I posted a more complete set of steps that you can use to clean up your system and reinstall the .NET Framework.  You can find them at http://blogs.msdn.com/b/astebner/archive/2008/03/07/8108332.aspx.

  • A great tool and a great description heads up

  • I keep getting an error msg. that tells me to stop Net\Framework\v1.1.4322 so that computer can enter standby mode. How do I do this?


  • Hi Penny - I haven't heard of this type of error before, so I'm not sure what to suggest.  Could you list the exact error message, or post a screenshot of the exact error message so that I can take a further look?

  • my mircosoft.net framework3.5 service pack1 and net frame3.5 service pack1 and .net framework 3.5 family update for .net versions 2.0 through 3.5 (kb951847 )x86 will not download it keeps saying failed

  • Hi Ray - Do these versions of the .NET Framework fail to download, or do they fail to install?  If they're failing to download, I'd suggest trying to download them manually instead of letting Windows Update try to download them for you.  If they fail to install, can you please use the tool described at blogs.msdn.com/.../6458047.aspx to gather all of your .NET Framework setup log files, post the file named %temp%\vslogs.cab that this tool will create to a file server (such as http://skydrive.live.com) and then reply back here with a link I can use to download your log files and take a further look?

  • I would like to have your NET Framework de-install and re-install tool  Windows XP Home

    Microsoft's advice seems useless. Everything on my computer dealing with security items seems blocked,

    but nothing shows up on Bitdefender anti-virus or Malwarebytes free.

    Microsoft fix-it did get NET Framework 2 and above to accept an update, but, it seems they deleted 1.1,

    and the auto-uploads keeps sending the download of NF 1.1 my way, but it won't upload

  • Hi Eldon Warman - You can find download information for the cleanup tool in the user's guide at blogs.msdn.com/.../8904493.aspx.  Hopefully the tool will be helpful to you in this scenario.

  • security updates for framework 1.1sp1 will not install when downloaded.can you help please

  • Hi martin - I'd suggest using the steps and the cleanup tool described at blogs.msdn.com/.../8108332.aspx to fully remove the .NET Framework 1.1 from your computer, re-install it, then try again to install the .NET Framework 1.1 SP1 and any additional security updates that are available for it.
