I installed Autodesk Simulation CFD 2013's license file onto my license server where my other Autodesk licenses reside, but I cannot get the Simulation software to run. I get two different errors.
A valid license could not be obtained by the network license manager.
Then I click close, which prompts me with Error #2.
Interface license cannot be accessed.
I have the license file, it's copied correctly from the INCREMENT section. My license manager serves up my other Autodesk licenses just fine. So I know it's not the LMTools.
Check if the Registry Value HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\Simulation CFD\13.0\Locale is set to "en-US"
so far I can remember, I had "de-DE" and the same problems.
-15 is typically Firewall blocking the 27000 or 2080 port or the client is trying to connect to the server via IPv6. If you have verified that the license server is up and running and licenses are showing available in the status enquiry, then you might want to check connectivity.
For more information about Network License Manager connectivity issues and IPv6, please see my discussion post here:
