You must extract all files in a directory; then with Virtual Cd or similar program you have to 'emulate' a CD pushing the files in the relative image.
So you must launch setup from the image ... and all is ok !!!
I reply with a question:
do you know why Mocca in C4D8 doesn't work ?!?!
I've substitute mocca.cdl with new given by someone here but nothing happens: when I change gram frame 0 to frame 1 my system crash (Win2000)
Thanks a lot
