No you can't have daemon tools installed, you'll need to use sd4hide. @tao welcome to the dark side! After an errorless install, I still get the please insert correct CD message when I try to play the game, my LG DRD8160B does already have the latest firmware, I have no suspect programs installed, I can't try sd4hide as that won't run on Windows ME, the PIO thing doesn't work. Nothing will get it to acknowledge the disc is in the DVD drive. Looks like I'm going to have a lot more time for Civ 3 until get a new DVD player.
