I just upgraded to Visual Studio 2012 from 2010 and a bunch of the winforms that use the NetAdvantageTM  2006 Vol. 1 CLR 2.0 plugin are not working. I tried running the same projects in VS2010 on the same machine and the same errors occur. I also tried removing VS2012. It seems that installing VS2012 changes settings in VS2010 which are not reversed when it is removed from the machine.

How should I go about fixing this? Thanks
