"Game not properly installed" error

I recently had to change back to my old motherboard for a while, and now PES4 doesn't start. I get an error box saying "The game is not properly installed", although I haven't changed anything, I know why this is - the keys in the registry are missing, and although I could fix this by doing a re-install, I don't want to do this because i've done lots and lots of patching and have so many files that I dont want to risk losing. So, could anyone please tell me the registry keys I need for the game to think it's properly installed? :)

Cheers
