In this section we aim to provide you with all the information you need to understand how your license works, and what to do if you experience any problems.

The Foundry Licensing Tools User Guide tells you everything you need to know about licensing Foundry products. Download the Licensing Tools User Guide here.

Managing floating licenses

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.

Note : 

We do not recommend using a mobile server, like a laptop, that doesn't meet the following criteria : 

1. Static IP
2. Static Hostname
3. 'Always on' status so clients can connect to the server over a LAN
4. DNS enabled
Problems will occur if you choose to use a macbook pro as a server, as it will not meet criteria point 2 above, and it will change hostname constantly when plugged into different networks.  This will need to be resolved by your Network or Systems team to resolve any hostname resolution issues that are found.
