Nefud A few questions questions. Is the disc an original? If it is, allow the disc to run it's self install when you put the disc in the drive. Are you able to copy the disc onto your HD, i.e. can you read the disc ok? The game doesn't run within a DOS shell! Most of the problems are graphics related when considering D2K and XP, compatibility usually helps then, but not with installation. What programs are you running when trying to install? Close down any virus software prior to installation. What service pack are you running? SP2 may create issues? I run D2k on XP home without the compatibility mode. No installation problems, just a few graphic issues needed sorted.
