Just read the damn instructions! It's really not that hard.
So do that, start the game and see if you still don't have any music.

1. Make a clean installation of Fallout 2 (humongous install). If you are running Visa/7, be sure to NOT install in the c:\program files directory.
2. Download and install the RP (only use the manual install if you really know what you're doing)
3. That's it. Don't install anything else, unless you know what you're doing!

Windows installer (recommended): download
