This was the answer. Loaded the contents into that folder and then tried again and it went right into the install.
Kevin, you were also right, I was trying to launch straight from the .ISO which was incorrect. I was reading how to "mount an .ISO volume in DropBox" online and that sent me down the wrong path.
Does anyone else remember this game Earth Treks from 1993?.... I played the shit out of this in our school's apple computer lab. Took me a long time to even find the files for this game and now actually get it running. The audio isn't quite right, so I might try the IBM speaker instead of the Sound Blaster and see if that fixes it. But overall super satisfying and really nostalgic, haven't see this in 25+ years, good stuff!
Thanks for all the feedback
