Check with the discs thats came with the computer. If one of them says "Microsoft Works" then put it in and see if you can get it to install it. You might have to access the disc via Windows Explorer and double click on the icon that says "SetUp". However if you do not have a disc there is no way to recover it. Word is the better version of Works though, and it can read Works documents, so I'm not sure why he want it back when he has Word.
