I have had to do something like this when trying to run an older Pg music program like the Jazz guitarist to a vista or windows7 machine . I copied the font from the old computer to a floppy or cd. Make sure you get the right font.
I think the newer pg fonts have a slightly different name. You want the old name.

I think in one case I had to "install" the font not just copy it. Try fonts in the control panel and see if you can install from there.
