You can try the official MS answer they post there. If that doesn't work, further down someone has a suggestion to run a repair reinstall of Windows (which, now that I look a bit more closely, seems like it may be the way to go, since the error is the program trying to run something designed for Vista and not Win 7). Essentially, boot the computer using your Win 7 disc, but there should be an option to run a repair installation instead of a full one.
