Worked with VMware Fusion support to determine the issue. vmware.log file was analyzed and the issue detected was "If you more than 8 network adapters on a cDOT simulator, VMware Fusion 7.x throws internal error message and fails to bring up teh simulator".


From the directory where cDOT simulator is stored

1. Delete *.lck files

2. Delete *.vmss files

3. Delete *.nvram file

4. Delete network adapters 9 and 10. Make sure cDOT simulator has 8 network adapters.


Poweron the simulator and VMware Fusion successfully brings up the VM.

This would work on FUsion but if you want to install it on ESX 5.x I found this helpful too I made all the steps mentioned on it and created the following OVA to save work to all of you
