Microsoft SQL (and other programs) crash due to mscorwks.dll

This kind of crash seems to be provoked in systems where several versions of .NET Framework are installed. About my case, I had .Net Framework 2.0 SP1 and .Net Compact Framework 2.0 SP2 (and also 3.0 and 3.5).

Just uninstalling .Net Compact Framework 2.0 SP2 solved the problem :)

In another case that I had, it was way harder, as I was not able to uninstall or reinstall any of the .Net frameworks. Luckily I found here the solution to my problem (http://blogs.msdn.com/b/astebner/archive/2009/02/18/9432938.aspx). It seems there is a tool coming with the framework that allows to you to repair any damaged file/registry key related to the framework.

Ciao!
