Not sure what you're talking about... Make sure you're downloading the 64-bit version, antivirus programs don't seem to like the 32-bit version for some reason
I've tried downloading both, it says I need permission from the administrator. I can't download it in my regular download so I chose a folder. It worked, but that's when I got the same response about having permission and the game either deleted or disappeared. I'm really confused on what's wrong.
That very much sounds like antivirus software getting in the way. Unfortunately I don't know what causes these false positive detections so there's nothing I can do :/
