Secrets of Feydwar disc, huh?

[Spidersfury]

I am absolutely losing my mind trying to install P99 on my PC, i have no clue at this point on how to do it. I cannot have the live version, okay, i get it. The only physical copy i have is the Secrets of Feydwar discs, so i just installed them. I have not bothered doing anything else at this point because i know it will just end up bad. Can someone PLEASE tell me what i need to do at this point?

I know the "directions" say you have to "download" P99, and extract the files...somehwere? This is the most frustrating attempt at installing a game i have ever had. Where the heck do i go from here?
