I'm trying to track it down, because I installed most of Telerik's Controls... Ajax, ORM, Winforms, Silverlight, MVC, Kendo, etc...
EDIT: I've found the installers causing the problem. Installing either the ASP.NET MVC or Kendo UI for ASP.NET MVC causes Visual Studio 2012 to fail. If they are installed, any project or solution you open new or old, regardless of it's type (web, winforms, class library) you try to open causes Visual Studio 2012 to fail with the error below.
Telerik: I'd like to get your input on this. I've tested in on two different systems (both running Windows 7 and Visual Studio 2012 Premium), and the same thing occurs.
Falling back to all the versions I had before (which takes a REALLY long time to do), fixes the problem, but I haven't tracked down which installation is causing the issue... yet.
Opening up any project or solution, new or existing, I get this after Telerik Controls Installation...

Telerik, do you have any suggestions?
Community, have any of you run into this?
If I can track down exactly which installation is causing the problem, I'll update this thread.
