Visual Studio 2005 crashes when modifying any file or project property

Ok, this one is a bit bizarre. If I modify ANY property in the file or project properti开发者_开发百科es dialog, Visual Studio 2005 crashes. Right-click file or project, select Properties, change anything => goes boom. Happens with both C++ and C# projects (haven't tried any other project types). I don't have any add-ins installed and it happens both with existing and new projects. I haven't installed any new hardware or drivers recently; the only changes I'm aware of are upgrading Chrome, Firefox (and plugins), and a Windows update for time zones; doesn't seem likely any of those would cause this. I've tried running with /safemode and /resetskippkgs command line options and neither helped. I would like to avoid a reinstall if possible as VS2005 is particularly painful in that regard. Anyone seen anything like this? My google-fu was not strong. Any suggestions?

EDIT 1:

Event Viewer has the following:

.NET Runtime version 2.0.50727.3623 - Fatal Execution Engine Error (7A0BC58E) (80131506)

Using my google-fu I eventually came across KB963676 and KB981574. Unfortunately, the available hotfix didn't work for me.

Well, I figured I would try to repair the .NET Framework 2.0 framework (this MUST be done from a command line) before trying anything more drastic. Lo and behold, it worked! Perhaps someone else will run into this and find this question.
