That's very strange. Seems some mess has occurred when copying it from WS. Probably the 'old' WS machine has been named WIN7_64B. There is only 1 .vmx file - TIA.vmx, but there are 2 .vmsd files - TIA.vmsd is empty (that's why there are no snapshots visible in the client), while WIN7_64B.vmsd refers to a snapshot - WIN7_64B.vmdk. OTOH TIA.vmx refers to WIN7_64B-000001.vmdk as disk file.
A safe way to proceed is to power on the machine and do a P2V. Thus it will clone the data as seen by the GOS notwithstanding any snapshots.
If you feel like hacking, you may try to rename WIN7_64B.vmsd to TIA.vmsd (after first backing up all VM files!!) to see what can be done with snapshots. However I don't feel confident what to expect. Also may be hostd might need to be restarted
