I'm using Inventor 2011 on Windows 7. When I try to start Inventor, I see a dialog box informing me that "Your application was not able to obtain a license because the FLEXnet license server manager could not determing where to find the licensing data it needs." Upon providing the location of the license file, I receive the error "A valid license could not be obtained by the network license manager," with Error [-15.570.0]. I've edited the hosts file, and I've also tried the solution shown here: http://220.127.116.11/t5/Installation-Licensing/err
For installations on Windows Vista/7 when the NLM is on Server 2008 or another Windows Vista/7 machine, then the -15 error is typically due to a connectivity error with IPv6. I have a KB on this issue in the forums.
For more information about Network License Manager connectivity issues and IPv6, please see my discussion post here:
Hmmm. I forgot to mention that the NLM is running on a Mac OS X server. So I don't think it's an IPv6 problem. I can ping the hostname from the client and I'm returned an IPv4-formatted IP. Any other possibilities? Thanks for the replies!
Are you sure you have a valid adskflex vendor file and Autodesk license service created on your Mac? Can you do a status that shows you have available Autodesk licenses? You're probably better off moving to a Windows Server.
Everything should be there (it used to work just fine, and then something apparently happened that caused it to fail), unfortunately I don't have immediate access to the server to check. I'll talk to the guy who does tomorrow and see what I can find. Thanks!
Just so everyone knows, I got the problem worked out. I reinstalled the NLM on a Windows 7 machine. I believe the issue involved the server host name on the Mac server expiring, but the reinstall fixed the problem without too much difficulty. Thanks for the help!
