      Unable to Stop Server. Check the License search path and VD status.


      This error may occur due to an incorrected configured service or ports, or an incorrectly modified license file or a permission issue or an older version of the software.

      LMTools might not reading the correct license file.

      In LMTools under the 'Start/Stop/Reread' tab, at the bottom of the window you will see the file path to where the license is located.

      Forwarding Ports

      Please make sure that the ports are open

      • FlexLM Port: the default port is 27000
        • If you have another License server running on the same machine or cannot forward the default port, you may change it through the Licensing Server Software

      • Daemon Port: by default uses a random port in the range range 49152 - 65535

        • You may fix it to a specific port in the Licensing Server Software

      How to change the Port Numbers:

      1. Start the Luxion License Server application.

      2. Go to the Install License tab.

      3. Click Set Server Ports.

      4. FlexLM Port: Change this to avoid port conflicts.

      5. Daemon Port: This is only used for network setups with a Firewall.

        1. If a Firewall is used, both ports need to be set and opened in the Firewall.

      6. Click OK.

      7. Click Reread License File to make sure the changes are applied.
