This error code can appear if there is another instance of the Luxion License Server already running on your host computer.

Below you will find a guide as to how to check and stop any open License Server applications.

On a MacOS:

  1. Close the LuxionLicenseServer application
  2. Open a Terminal
  3. Use the command: ps -ax
    1. This will give a list of all applications currently running, it is more detailed than the one in activity monitor
    2. This list is sorted by the PID
  4. Locate the license server process called something along the lines of:
  5. Note the PID
    1. In my case it was 111, but I believe this varies
  6. Use the command: sudo kill -9 <PID>
    1. In example: sudo kill -9 111
  7. rerun ps -ax and verify no "lmgrd" or "LUXION" application is running
  8. Use the command: cd /var/tmp
  9. Use the command: ls -l
    1. You should see an entry like: -rw-r--r-- 1 root wheel 0 Dec 16 14:49 lockLUXION
    2. If you dont see that file continue to step 11
  10. Use the command: rm lockLUXION
    1. Note you may need to use sudo rm lockLUXION
  11. You are now done
    1. Open the LuxionLicenseServer application and setup as normal

If this fails:

  1. Open the terminal and enter: sudo nano /etc/hosts
  2. Check to see if the hostname used in the license file is listed
  3. If not, add a static IP address and the hostname from the license file
  4. Press CTRL + O, followed by Enter to overwrite the previous information
  5. Press CTRL + X to exit
  6. Launch the Luxion License Server app and press Install License
  7. Browse to where the license file is located and re-install the license
  8. The server should start automatically, press 'Status' to check if the server is running
