Let me first accurately describe what happened. So one of my HDDs failed (I got a new one, a Western Digital Caviar Blue 640gb). I had lot's of applications and games installed on the failed HDD, but nothing important. Now, when I go to re-install those games/apps again, some of them act as if they were installed, and attempt to uninstall (the hard drive failed so it was unable to uninstall the correct way). So, it will not let me re-install those programs, until I uninstall them. They are unable to uninstall because they cannot find "Drive D:," which is the failed drive, and they are probably still somewhere in my computer's registry, but the install directories are gone with the failed drive. If anybody knows how to fix this to reinstall my programs again, I would greatly appreciate it. I am on Windows 7 Ultimate 64 bit. Thank You.
