I ended up tossing the Wizgold folder into the C:\ directory to get it working. Had to make sure steam did the initial setup first as well.
I'm going to try making a guide of sorts for the game on there. If anyone wants to contribute, feel free to friend me on Steam and let me know. First order of business, direct folks to all the tools and community sites already available.
Also going to see about distributing the Windows Help files that came with Gold, and the map. They don't seem to be functional in the Steam version, even after downloading the appropriate classic Windows Help program. It still looks for them on the D:\ drive from the menu.
