Fix The Blue Screen Of Death On Your Pc

Visual Studio 2010 wont start after uninstall NET Framework 4 5 Unknwon error

I did some tests with .NET-Framework 4.5 on my computer. After uninstalling it, i recognized, my Visual Studio 2010 does not start any more. It shown an "Unkonwn error" message box at startup an then closes again.

How-I-fixed-it:
I found out, that uninstalling .NET 4.5 also uninstall .NET Framework 4. I re-installed .NET 4 from http://www.microsoft.com/de-de/download/details.aspx?id=17718 and Visual Studio was working fine.
