PLEASE NOTE: If you using a floating license on Mac or Linux, there is a known bug when attempting to install the license server tools via FLU version 8.1.6. Please use FLU 8.1.3 to resolve this. Further details can be found here: Q100630: Unable to install license server via FLU 8.1.6 on Mac/Linux

Known Issues

 If you install the server tools before installing a floating license, an RLM server will start on the default RLM port (5053). When you then install a floating license, the FLU may not be able to restart the RLM server on the correct Foundry port (4101). Uninstalling and reinstalling the server tools will fix this and you can avoid this issue by installing a floating license before the server tools


  • Login-licensing functionality
