I have done the full install of Myst III Exile on my system. I'm running XP Home and have a 1 Gig processor with an 80 Gig hard drive and 384 Mg's of RAM. When installing I tried to install the DirectX drivers but the machine wouldn't let me as that program doesn't run on Windows NT. I have tried all the compatibility modes and have installed the Ubi 1.2 patch. When I try to start Exile it keeps telling me to insert a the CD-ROM but it's already there. I've tried taking it out and re-starting but to no avail. Any ideas?
By the way, my system runs Riven and the old Myst just fine.
