I'm getting the same problem (Mac OS X 10.8.2, VMWare 5.0.2, RAM set to 1024MB).  The Vista &amp; Win8 VMs worked just fine, but neither Win7 VM worked at all.  I get the same repair failures that Matt says.

I've tried unzipping the archives through The Unarchiver and Pathfinder.  I've also downloaded the VMs multiple times.

Thanks.
