Q100105: How to generate a License Diagnostic Log via the FLU for troubleshooting license issues



If you are encountering any problems with your RLM node-locked or floating licenses and cannot resolve the problem using the information in Licensing Online User Guide or the Support Portal Licensing Help section then please generate a Diagnostic File from the Foundry Licensing Utility (FLU) and send it to us on a Support ticket.

NOTE: For problems with floating licenses, please generate an FLU Diagnostic file from BOTH the license server and a client machine running the application.


If you are encountering issues with your login-based license,  please follow the steps outlined here: Q100285: Troubleshooting individual login-based Licensing

If you have further issues, we may also wish to see a diagnostic log file for this to get more information about your machine.



The FLU can create a license diagnostic file for a machine to help with troubleshooting licensing problems.  A diagnostic files includes lots of useful information about the licensing setup such as

  • The machines hostname, System ID and IP address
  • Any license files installed on the machine and whether they are valid or not
  • If the server tools are installed
  • Server log files and license error log files
  • Advanced license setup info such as licensing environment variables and server options files

No personal information is gathered.
