I installed parallels on my macbook pro and i installed windows 7 iso via a DVD. at first everything looked fine exception now I am now trying to compile an asp.net-mvc app in visual studio and i get this error over and over

No matter what i click it will eventually progress but this is quite annoying. The same question was asked here but no good answer was given.
Can someone please explain why devenv.exe would need the ISO dvd to be connected to my laptop at this point?
