Unity mode still doesn't work in VMWare Fusion?

Hi, All:

I'm running VMWare Fusion (Professional Version 7.1.0 (2314774)) on Yosemite (10.10.2) and whenever I try to switch to Unity mode, get this helpful message:

For best compatibility, shut down the virtual machine, upgrade the virtual hardware compatibility to the latest version, and ensure that VMware Tools are up to date.

I've done the first part, don't understand the second part, and when I tried repairing VMWare Tools and restarting ... that didn't help either.

Any ideas?  I really miss Unity mode...

Thanks,

Michael
