The engine seems really picky about what version of VS you have as well as if you have multiple versions for whatever reason. I actually had VS2010 still installed due to needing it for some older stuff as well as VS2012 and was running into a lot of compiling issues like this one. I uninstalled everything VS and then installed VS2013 and now everything is working great.
