with My Computer or Windows Explorer on that DVD, on both this computer and the two you installed it on when the media still was OK. Set the Folder Options to "NOT hide extensions of known file types", and you should be able to find battlefieldxx.exe (.exe being the file extension for an executable file) in the root folder of that dvd (I prefer detail view in cases like this). Then run it by doubleclicking.
Post back your experiences.

By the way, does the license for the DVD allow multiple installs?
