Just trying to pin down the exact cause of this problem. I think it's another case of Microsoft issuing a security update which quietly compiles itself in to the IDE then the vcredist that's bundled with the installer becomes out of date. Very frustrating, especially since there doesn't seem to be any notice or warning from Microsoft... oh well.
Anyways I think the solution might be this:http://www.microsoft.com/downloads/en/d ... C13F19BC50
If this build had an error starting up for you, can you try downloading & installing vcredist_x86.exe from that link and let me know if the editor works/doesn't work afterwards? Thanks!
