Just downloaded it. The zip only contains the 64bit version? Trying to run it on a 32 bit win 7 and getting the error that this file is not compatible with this version of windows
Ok so I made a 32bit version (you can download it where the others are)
BUT, there is a high chance it will not work anyway.
I looked into that a bit more and it looks like there are problems with the newer Unity3D versions and Win7 (If that is the case you might just get a black screen)
I'm still looking if there is a way to get around this though, but there might not be one.
