The current version requires full blown boraland 7 (which can be had at <http://vetusware.com/download/Pascal%207.01/?id=3724>. I don't remember the reason Turbopascal won't work, but that is what the authors told me. V7 and windows7 won't cooperate either, so you will need to run that in a virtual box.
There are also more recent compilers out there that should work but I haven't tried them yet.
