I have this game and LOVED it when it came out and I played it the first time :-D. I don't know if this'll help, but most older games can work if you use DOS box.
I have a friend who has a site called the Sierra Help Page. Despite the name I'm pretty sure he also helps with other games. He is really good at getting older games to work on newer computers. If he doesn't know how to fix something already, he is usually quick to finding it out.
