I figured this out. I initally installed Inventor on a deticated PC thinking that Inventor running
in a Mac Parallels VM would not be up to the task. After installing it on the PC, I found that
I still wanted in on my Mac. So I put the post expanded setup directory on a USB drive and
tried to execute setup.exe which failed. Later just to give it a whirl, I put the two self extracting
files on the USB drive and ran them allowing the setup directory to be recreated. For some
reason that seemed to work OK..
The PC is better than Parallels, but performance is OK so far..
