After going through this Problem (connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=329986) that was related with registry permissions, now again, Visual Studio comes with another error.
I have the same error as this guy, I have searched all the internet and it seems nobody has resolved it yet.
When I create a C++ Windows Forms Application, and want to see the “Design view” of the the default Form1, it just gives me this error:
Invalid Class String (Exception from HRESULT: 0x800401F3 (CO_E_CLASSSTRING))

I’m sorry if this has nothing to do with programming at all, but if someone has any opinions or comments, I would like to hear it.

Well this hapend to me after i renamed feacp.dll in order to disable intellisense.
However, after re-enabling intellisense, all worked ok.
