Every time I try to open some of my games (Valiant hearts, Just cause 2, Far cry 3, Mount and blade: warband, ect) I keep getting Error 0xc000007b. I recently installed Windows 8 and I hated it so I re-installed Windows 7 again (Both were pirated) and now some games won't work, I have installed lots of .dll files and installed .NET 3 times and I've re-installed the games 5 times but nothing seems to work. Please help.
