Question

I have visual studio express 2012 and it was working fine earlier I had run my solution once. But now when I do it, there appears a dialog box with the message!

Answer 1

I had Visual Studio 2013 Professional and I got the same error. I couldn't remove it until I repaired VS installation. It took a while but now it works fine.
