When I open Visual Studio everything is fine, but when I open any solution, it comes up with an error:
Visual Studio 2012 for Windows Desktop has stop
If all above answers doesn't solved the problem. Try to disable the internet connection and then open the VS; if it opens without the error, It possibly means that the one causing the problem is the Instance ID / User account. Logout your microsoft ID (still without internet) and then plug the internet again and try to open the VS.
This worked for me.
