In order to use a floating license for products, you need to install Foundry License Tools (FLT) on your license server. Do not install these on client machines.
The FLT contains both FLEXlm and RLM license servers so they can be used to manage floating licenses for all The Foundry software.
Please refer to the Foundry Licensing Tools User Guide for instructions on how to run the Foundry license tools and float licenses on your network.
