Today I had a problem with VMWare Workstation on my Windows 7 computer. A while ago I rebuilt my laptop with Windows 7 RC, and I reinstalled VMWare Workstation v6.5, but I hadn’t opened any of my VM’s until now.
I managed to open up VMWare succesfully, but when I tried to start my virtual machine, I got this error:
Check for missing files failed: Insufficient permission to access file.
The problem is with UAC under Windows 7.
The solution is to open VMWare Workstation using the “run as Administrator” option.
