That program must be more than 20 years old. I don't see any good reason to use it now. And I don't fully understand why you can't use it at the moment. What copyright issues?

Anyway, http://vetusware.com/download/PFS%20Professional%20write%20_/?id=4902 seems to have it in a zip-file and there's even somebody who said it runs under Windows 95 in a command window.

But I must warn you: when I visited that link, my antivirus (Avast webshield) popped up and warned me it had blocked the page. So I would play it safe and visit that site only after booting into a Linux distro or from a Mac.
