You do not need to install the license manager if you are installing a trial version. The paid-for version on Linux, however, always requires a running license manager. Many of the instructions for installing the FlexNet license manager are similar to those for Windows. This section covers only the differences when installing on Linux. For general information on the license manager software, see License Manager Installation on Windows. In some cases, however, the COMSOL installation also installs and configures the license manager.
