@Behnam Mazdouri,

  1. Ensure that you are using only the workshop license file. 
  2. Remove the Lumerical preference.ini files from your computer. 
    • del %appdata%\Lumerical\*.ini
  3. Stop the Ansys license manager using the Ansys License Management Center web interface.
  4. Delete (move to a different location/folder) the "ansyslmd.lic" license file from the folder,
    • "C:\Program Files\ANSYS Inc\Shared Files\licensing\license_files"
  5. Add the license file that you received from Ansys Lumerical for your workshop. 
  6. Install the license file and Restart the Ansys license manager when prompted.
  7. You should only have the workshop licenses on your Ansys License Manager. 
  8. Try to open/run Lumerical on your computer. 

Let me know if the above works. 

Best,
Lito
