The version of Zork Grand Inquisitor sold by GOG now includes the open source Zengine, which runs the game smoothly on Windows XP, Vista, 7 and 8.

I'll update my guides on the Zengine Wiki and on my Zork Installation Guides website in the coming days to reflect this change.
I expect that they'll get their version of Zork Nemesis running with ZEngine soon too, because ZEngine supports that game too.
ZGI from GOG now uses ZEngine, supports Win XP, Vista, 7, 8
