I finally am up and running Fusion 5 with Mountain Lion
On my first attempt I chose share vs isolate mode. I discovered that my entire download folder in the Mac was transferred to the virtual machine (Win 7 professional). Not copied, taken. It may have also taken the desktop. I accidentally noticed this (a finder window was open on Mac) as I was attempting to get rid of all that unwanted stuff of the new virtual machine. I stopped the empty recycle function. Then I had a mess on my hands
Thank God for Apple Care and my Time Machine. Uninstalled Fusion and started all over after getting my Mac back where it should have been. Install good, but migration no. Now discovering more documentation to read before I write again.
Stay away from Share mode!!!!!!!!!!!!!!!!!
