You could make a ISO of the cd's and open them with Daemon tools...Then when installed just set Daemon tools to run the d2 exp iso and voila..It's driving like u have ur d2 cd in...The thin Daemon tools does, is that it makes a virtual cd cdrive, and when u then set a iso like d2 exp to run it looks like a cd drive and that u have ur d2 exp cd in it ....
