Hi I have an original red alert CD set (allied disk, soviet and yuri's revenge) and have a windows 7 64-bit on a PC. When I click install from the auto-run or directly click on the setup.exe nothing happens, not even an error message. I have tried running as administrator and with xp sp3 and 98 compatibility . No matter what I do nothing happens each time. I read a few posts and even tried to delete and reinstall MS-KB3086255 And still nothing happens.... Can anyone help me please? Thanks!
