I just looked at the Rocketship website. Drafter, have you not tried the free trial version? That'll be the easiest and most obvious way to check if PzDB can run on your Windows system. Then, if it does run and you like it, you can get a licence via the Payloadz service, which I've used and is fine and reliable (despite the slightly dodgy-sounding name).
