Yepp, doesnt help.
As i mentioned above, i had the same problem when i had WinXP (SP3), but could run it if i typed in my pw and ran it as an admin. Which then was really strange since my account had admin rights.
I'm guessing it has something to do with the securom or copy protection.
Its very irritating since i avoid pirated games.

What is really funky, is that it worked straight out of the box on my laptop, which is running Windows Vista Ultimate.
Only had tons of problem on my Desktop to run this game.
Windows 7, is as someone mentioned, Vista done right. All my other games has worked flawlessly on it. Just for some reason ArmA 2 dont work well on it.
But when it ran under WinXP (started manually everytime by me punching in my user pw) it ran very well.
