You need the license manager to run the COMSOL Multiphysics® software using the FNL, CKL, or COMSOL Server™ license types. This video tutorial explains how to set up and start the license manager.
The process for starting the license manager is the same for both start-comsol-license-manager and COMSOL Server™. If you have both of these installed, you only need to start the license manager from one of the installations.
Note that the tutorial installation is performed for version 5.0, however the steps are the same for future versions.
For more information, please read our installation guide.
