I am experiencing the same issue. Let me know if there are any logs that I can provide that would help

I believe this was caused by uninstall the Visual C++ 2010 Runtimes. I did a system restore back to before uninstalling the runtime, then tried running the .NET Framework 4 Extended Beta 1 uninstaller, and it worked

how can i reinstall vs 2010 redist? WCU\VCRuntimes\x86\vc_runtime_x86.msi does not install directly..

I confirm that its related with Visual C++ 2010 Beta 1 Runtime x86.. to force install vs 2010 runtime from setup cd, type cmd:
msiexec /i vc_runtime_x86.msi ADDEPLOY=1

Hi Gokhan,

Thank you for your feedback. This is a known issue due to the C Runtime is uninstalled on your machine. This will be fixed for Beta 2 release of .NET Framework 4. For uninstall of Beta 1, you can ignore these messages as they are benign errors.

Thanks,
.NET Framework deployment team

I'm getting this also, after uninstalling VS2010...Currently .NET 4 will not Repair or Uninstall, both fail/rollback.
Many apps on Vista, including Microsoft Security Essentials, are now throwing these errors:
MSVCR100.dll was not found
\v4.0.20506\mscoreei.dll could not be loaded

If you're operating on an x64 system, you'll need to reinstall both the x86 and x64 VC runtimes, as given above.

I have uninstalled VS 2010 beta 1 and .NET Framework 4.0 Beta and have the same issues. My system (Windows Vista) can't start MOM.exe (ATI video driver component), Internet Information Services (IIS) Manager and other applications, the error is "... MSVCR100.dll was not found. ...".
