Ok, so we were able to find a solution. This was not related to EPiServer at all.
The project had a reference to System.Web.Mvc.
When you install VS 2012, MVC 4 is installed in the GAC.
The project was referencing an old version of MVC (v2) that was also in the GAC of the old dev machines.
VS was able to build even if it was resolving the wrong version of MVC, but in runtime it crashed.
The solution was to reference System.Web.Mvc version 2 directly/explicitly, not through GAC.
Hope this info can help someone else. :)
Hi,
I am setting up our EPiServer CMS 6 R2 web site on my Windows 7 (x64) OS, having copied the code from TFS that was developed on 32 bit Windows 2008 Server, and also switching from VS2010 to VS2012. Compiling the project goes well, but when I try to load the web I get this message:

I found someone having the same problem on the EPiServer forums, where the soultion was to uninstall MVC 3, but that solution does not work for me. I have uninstalled first MVC 3 and then MVC 2, testing between uninstalls.
Any suggestions on how to fix this?
Are there any differences for the x64 architecture or for VS 2012 in the web.config file(s), for instance? I copied those from the old install.
