Cannot install the game

[Kostya]

Apparently he doesn't have any anti-virus. /facepalm

All he has is Spybot Search and Destroy, which is just a Malware/Spyware remover.

Unfortunately he doesn't really have another computer to use to make a copy of the game, and honestly his drive may be the problem - apparently it is a bit finicky. I guess I might end up making a copy for him and sending it to him so we can rule out the disk being an issue...

Edit: Apparently he has some anti-virus, but it was already off. ._.;
