I converted a VM from an ESRI server down to my MacPro and can run the VM there with Fusion4. I copied the files over to the MAC mini and get a "Make sure you have rights to access the program....."
I used Fusion 4 on my MacBook to connect to the VM on the mini and it started up without any problem. Every time I attempt to start a VM with Fusion 5 on mini I get the permissions error. The account being used is an administrator account and is the account that installed the program.
I checked permissions on the converted VM and that doesn't seem to be the problem.
Should have added:
Hardware: MAC Mini
OSX Version: 10.8.2
VMWare Fusion: 5.0.2
