Hi, As some of you might know I finally managed to get my computer working again, and believe you me it took a lot of work…. I lost nearly all my data, only managed to save a few games. However now, when I try patching my games I see this sort of error message come up “………………. Is not installed or corrupt please install/reinstall”, I think this is all down to the fact that when you install a program it writes data etc. to the registry telling the computer its installed and can run. But because I lost my entire registry I now cannot patch or in the worst cases not even run my games. This is where you come in… If any of you have any of the following games installed and are willing to help me out please private message me or contact me through email@example.com, cheers. And if you don’t know how to look through the registry go to Start->Run->Then type in “regedit”. Or alternatively go to your Windows directory then find the .exe called regedit. Thanks, games are: Halo, Manhunt, Battlefield 1942, Joint Operations, Doom 3, Warhammer 40,000: Dawn of war.
