Inventor 11 isn't very compatible with vista RC2.
I have to dig down into the CD to find the install folder...change the
compatibility mode of the setup.exe to winxp and run as admin.
Then after it installs I have to change the compatibility mode of the
inventor shortcut to winxp and run as admin.
Even then I'm still have issues with the content libraries not showing up
and a few other minor issues.
It could be because of the way I installed it, that I'm missing things.
So I can get it to run, just not fully.
It's sad that such a large company can't get their act together.
