So I go to install this game and I keep getting error messages saying there are files missing as it's trying to install. I went and returned the game and got another copy. Same thing happened. So I reset my bios to get everything back to stock speeds made sure my optical drive is working by installing some other programs and everything. Still won't install. Then I go and try plugging my optical drive into different SATA ports on my mobo and still refuses to install. Tried moving my SATA hd to different SATA ports and still won't install. Does anyone have any idea what I could try to get this game to install? It's really driving me nuts here.
