You don't need the CD, but I haven't been using it long enough to try uninstalling MIMIC1 yet (SHOULD be just fine - DAZ installers only check for old versions of stuff on installing, not every time the program is used). Hmmm... I note that it's not quite as good as Poser at finding textures... looks like I might have to correct some references (and the MilDragon doesn't work quite as well with MimiC 2 as I'd have liked - but such is life).
