After re-installing CFX11. on my computer, a message prompted out every time when I tried to run CFX-Pre (and CFX-Solver mananger, CFX-Post....), which says:

"Aborting due to unexpected error: socketError: RemoteEngineProtocol::receiveTransStat - Communications error: unexpected end of transmission from engine, expected status code."

but i have used same license file for my ICEMCFD 11, it is working fine can any body hep me in this issu.

Maybe this is a general problem, since my colleague encountered the same problem. Did you ask the Ansys guys for help? Would be interested in any solution you found, since he also couldn't fix that problem so far.

You can delete the folder c:\documents and settings\<username>\.cfx and then try again
