You sure you're looking in the installation directory? Typically in C:\Program Files\.... whatever the default directory was.
sound.xp3 is a 360MB-ish file. F/sn won't work without it, period (it will crash on you like an ass).
It's there, and I don't think it can be anywhere else away from the installation directory and still work.
....might have to try harder, or employ the services of Windows Search.
