Yeah, with the windowed version, it would just open a white window. Nothing would happen afterwards.
I can see on the process list that it uses up about 191mb of RAM, windowed, but in fullscreen it eats about 153mb. That's essentially the only difference I can get out of them.
I've verified the files via steam and it turned up nothing.
Backed up the Steam files, deleted all data and restored. Nothing.
Downloaded the VC++ 12 Update 4 which I saw mentioned, nothing.
Is there a tool I can run that is going to give me some more specific informaiton?
