Dude, my mate has the same problem as you, he has little knowledge on computers and so do I although i have a little more than him, I've been trying endless troubleshoots for him on websites including this one, but i have got somewhere with this, just a couple of questions...
1) Are you an admin on this computer
2)What your computer specifications are
If you have this on steam we do too so it might have something to do with this steam item, once again i dont know.
This is the other thing i have tried
1) Computer > (Hard disk Name) > Program Files(x86) > Steam > steamapps > common > Arma 3
2) Then right click the 'arma3' application
3) Click on properties
4) Click on 'Compatibility'
5) "Tick" disable visual themes + "Tick" Disable desktop composition + "Tick
But this didn't work for us because my mate wasn't an adim on his computer, we changed that BUT it wouldn't let us tick "Run this program as Administrator"
I'm not sure if this did anything but I think we got somewhere on this^^^ :)
I have tried to change things in his firewall allowing programs through but i don't think that has anything to do with this.
Graphics - Is your graphics card up to date?
This is vital to make the game run.
This is all my intel on this case but i'm not so sure what your knowledge is like on computers but I hope you get this game working, it would be a shame if that £19.99 went to waste...
