Uninstalling VS.NET 2010 Beta Breaks .NET?

Question

I've been running VS.NET 2010 beta for a couple of months now alongside VS.NET 2005. As late as yesterday afternoon I was using 2005 for work.

Last night I uninstalled VS.NET 2010 and nownone of my .NET-related apps work (VS.NET 2005, SQL Server Management Studio, etc.). The installs for these products won't work, either, nor will the 2.0 SDK or 2.0 Framework installs.

They're all failing with this error:

(Msgbox title) ngen.exe - Unable to Locate Component
This application has failed to start because MSVCR100.dll was not found.  Re-installing the application may fix the problem.

Which, of course, it doesn't, since this is the install.

Any ideas? Google doesn't seem to have anything.

Problem Solved. The answer is...uninstall .NET Framework 4.0. The VS.NET uninstall doesn't take that with it, and apparently DOES remove the VC runtime dependency
