I upgraded to Windows 8.1 this morning. When I started Visual Studio 2010, I got the following error message right after the splash appeared:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Microsoft.Vsa.tlbcould not be loaded. An attempt to repair this condition failed because the file could not be found. Please reinstall this program.
Once I dismiss the error, Visual Studio loads up. Everything seems to be running ok, but everything I'm working on is using Framework versions 3.5 and greater. Should I be worried?
