Make sure you are running it out of a user directory, like in Downloads or Documents. If that doesn't work, try running it with admin privileges.
No luck, sadly. Earlier it was indeed on the downloads folder, but now I unpacked it to a folder directly on main C drive.
The first screenshot is without admin privileges, and the second one with admin privileges, it didnt seem to make any difference.
I'm on x64, Windows 8, if that helps.
oof yeah windows 8... try compatibility mode? can't really help beyond that, windows 8 is a terrible operating system, good luck
