the reason i post this here is because i've only had this problem on XP and not any other OS. i usually make ISOs of my games and put them on my hard drive so i do not have to change cds when i want to play a game. i use Alcohol 120% for this. always worked for me on 98SE and 2000. but on xp, i can mount it fine, and install it fine, but when i try to run the game, it tells me to insert the disk, when it is already mounted on a virtual drive. what's causing this? is there a setting i need to have on to be able to do this or something? *edit* it also happens with Daemon Tools
