I was working on a project that required me to make a .msi installer for it. Whenever I would try to build the wix project, my Visual Studio would crash with an uncaught exception. After some trial and error, I was able to determine that having both Wix and Visual Studio Achievement would cause the crash.
I am using Visual Studio Ultimate 2012, and unfortunately I am unable to get a stack trace, or anything to that effect, because it is an uncaught exception.
