One of my friends had an illegal copy of Jazz2 (he didn't know it wasn't abandonware so don't not answer because of that) and when he discovered this he then asked his mum and she won him a legal copy off ebay. But now the setup thinks he has it installed and can't find the path to the unistall file so he can't get rid of it and reinstall it. He want's to nkow now how to remove it from the system registry so the computer thinks it's gone OR what the original path for it is so it can find it. Please help.

BTW this is the same friend who couldn't get a legal copy I asked about a while ago.
