I copied a VM from my archives, one that was operational some years ago. When I try to run it I get the message:

Unable to open file "F:\VMWare\SoftwareDev3_x64\Windows 7 Pro x64-cl1.vmdk": 

The system cannot find the file specified.

The files does exist but Workstation is not able to use it. I have searched here for a solution but so far have not found a way to start the VM.
