don't instal games and etc under the standard direcories, that may bug up the game, since vista\windows7 have some type of protection at those folders, if i remember right, and if you have paid for your farcry, you can just download a "piratecopy" iso from a torrent site, and then use your own cd'key:) and you said your cd was broken or something? just download a no-cd patch. nothing of this is illegal, if you already has paid for a game, there is nothing wrong with this as far i can tell:)
