What version of the game did you download? Also, did you extract the file with admin permissions?
The current pc version, I just redownloaded it to be sure and it's still an issue. I don't know about extracting with admin, I just use 7-zip, I've tried running it as admin but still no dice.
There's two .exe's. One's for 32bit. Make sure you use the one that ISN'T labeled with 32.
I've tried both multiple times.
