Can't install Yosemite Guest on Fusion Pro 7.1.2

Odd issue here.  I'm running Fusion Pro 7.1.2 and can't install Yosemite as a guest inside 10.11 El Capitan...

Step I've followed:

1. Downloaded Yosemite from the Mac App Store and moved the file into the ~/Downloads folder
2. In Fusion - create a new VM using the "Install OS X Yosemite" file.
3. Accept the defaults and save the VM to my local virtual machines folder.
4. The VM boots first to the black Apple menu (and progress bar), and then into the OSX Utilities menu as expected.
5. Here's where I get stuck.  I choose "Install OS X" and click the Continue button, but nothing happens.  I turned on the Installer Log viewer and see an error:

OS X Utilities[487:12972] Could not launch application.  Exception: launch path not accessible

I can launch the Disk Utility and do see a Macintosh HD formatted and ready to accept the OS as you'd expect.  I've even deleted that drive and recreated it successfully, but each time I return to the OS X Utilities menu, I can't proceed.

Help?

Thanks,

Bryan
