    • New Floating license file


Please follow the steps below:

Attempt to Launch LMTools:
  • First, try launching LMTools. If you're unable to do so and encounter issues with file paths pointing to non-existent folders, it's possible that LMTools might not be installed.
  • If LMTools cannot be launched, I recommend contacting your IT Admin. There might be a firewall setting preventing its installation with the server installation package.

Update LMTools File Paths (if LMTools can be launched):
  • If LMTools is successfully launched, update the file paths as follows:
    • Path to the lmgrd.exe file: C:/Program Files (x86)/Luxion License Server/lmgrd.exe
    • Path to the license file: <Enter the file path to the License file>
    • Path to the debug log file: C:/ProgramData/Luxion/License/LUXION.log
  • Note that these are the default settings, and you may have alternative configurations.

Save Changes and Start the Server:
  • After updating the file paths, save the changes and attempt to start the server using the Start/Stop/Reread tab in LMTools.

Please keep in mind that the instructions provided are based on default settings, and variations may exist depending on your specific setup. If you encounter any difficulties or have additional questions, please feel free to reach out. We're here to assist you. Thank you for your cooperation.
