I recently bought The 7th Guest Game off of Ebay. I remember having trouble playing it when I was younger because my computer was too slow. Not it seems my computer is too fast or advanced, and I can't figure out how to load it. There have been other posts on this topic, but for someone who is pretty computer illiterate, I don't really understand what to do. Can anyone please help me out? Please tell me how to install this game correctly (windows 2000) step by step. thanks in advance!!!
