ARRRGHH!!!  Don't frisbee the disc!!!!!

I just picked up the 3DWorld issue with both Carrara 7 Pro and Mimic and it installed fine.  There didn't appear to be a button to install directly from the DVD though, so I clicked on the open folder containing files (or whatever it was).

1. That aside, can you use your Operating Systems Explorer to view the contents of the DVD?
2. Have you tried the DVD in a different computer or drive?
3. Since this is a double sided DVD, have you flipped the disc over to see if that side works?

If none of the above works, than you may have a bad disc.  Or, if only 1 side of the disc works, then it may also be a bad disc.  There is a contact listed in case such a problem arises.

If the disc works on another computer or drive, than you may have a bad DVD drive or it is only a CD drive.  I have had drives go out of alignment and some discs work and others don't.  It eventually gets worse, so I ended up buying another drive.

If you can see the contents of the DVD through your OS's Explorer, than just go to the folder and install from there.  This may also indicate a bad or corrupted DVD in which the part of the disc that loads the program is pooched.

Hope this gives you some things to try and narrow down the problem.
