License server backward compatibility

    • heechangna

      I updated the ansys license server for 2022R2 version.
      And, noticed that it is not working for the versions older than 2021R1.

      I have tested for 17.2, 18.1, 19.1, 19.2, and 2019R1: these are not working.
      But, 2021R1, 2021R2, 2022R1, and 2022R2 versions are working fine.

      When I run a job with older versions, I got messages:

      ANSYS LICENSE MANAGER ERROR:Capability Fluent Solver does not exist in the Ansys licensing pool.

      The specified license path:


          FLEXlm Servers:

      does not have any licenses for any product. Please make sure

      the license server has been started correctly.


      Invalid returned data from license server system.

      Feature:       fluent


      License path: -


      FLEXnet Licensing error:-12,16

      For further information, refer to the FLEXnet Licensing End User Guide,

      Any suggestion would be very helpful!

      If you open the Client License Preferences for the older versions and choose:
      Reset to Default.

      Does it show the licenses in the list?

      What is the output from choosing a license status from the client machine?
