Problems installing a game...

I’m trying to install Planescape: Torment off of a copy burnt from an ISO. When I put it in, the standard rigmarole of setup screens appear and I attempt the installation. When said installation gets to 6%, I get the following error message.

Does anyone here know what the problem may be, and more importantly, how to correct it?

Cyclic Redundancy Check, or CRC, means… okay, I have a headache so I’ll spare you from my masturbating my meagre know-how of informatics:

Data is corrupted. Your disk is probably fuxxored. Get a new one.

Got it working. Thanks.
