I can't find any tech support for the game. Many user reviewers in Steam couldn't get it working, or only got it working briefly. Best way to run it seems to be on an old computer with real Windows XP (not compatibility mode) and a video card from around the time the game was made (2005) with video drivers from around that time.
Maybe a few people were able to run it somehow on newer systems, but the bulk of user reviews say it's impossible
