Visual Studio 2013 Ultimate crashes upon opening and Unreal project

Hi ,
I’ve only had a to try it using 4.5.1 and 4.6 but it does crash with both versions of the engine. I also tried using a version compiled from source on another computer but that also resulted in Visual Studio crashing. I can see that the project starts to load and the files appear in the Solution Explorer but then the program crashes.
I was also able to make the error in the activitylog go away by uninstalling the Windows SDK which I had installed a while back to use their debugging tools, but unfortunately it didn’t solve the crashing problem.
