Local TASKING License Server (not applicable to evaluation licenses)
If you have ordered a TASKING product with a floating license, you can have it serviced by the
Remote TASKING License Server (the most convenient solution) or through a Local TASKING License Server
(in case you have no external network access for example). Consult your TASKING representative for
assistance on deciding what the best setup would be for your situation.
If you like to setup up a local license server, we kindly refer you for more information to
Support for TASKING License Management System (TLM)
on our website. Here you can also download the Local TASKING License Server package.
It is advised that you install the Local TASKING License Server before you install products that
