So, I got a new computer, and it has Windows 7. I really want to enjoy Heroes 5 on a big monitor. I'm trying to install it, but I'm getting an error.

Did you clean the registry?
Yes, there are no files related to Heroes there.
Did you disable the antivirus?
Yes.
Did you check the disk for integrity on another device?
Yes, Heroes installs perfectly fine.
It's a shame to reinstall Windows... Does anyone have any ideas, and could it be something else?
