I purchased Dell Latitude 3540 a few days ago which has 8GB/1TB/2GB graphics.I tried installing games- "Call of Duty","Modern Warfare-1","Battlefied-3". But all the time it says some file is missing. The same files when run on another dell but diff model-viz Inspiron,ran quite well. I fail to understand why these games are not able to be installed here. If its a case of missing files then where from these can be downloaded as I have downloaded these games from torrent site.Any help is welcome.Thanks.
