Avanti and AvantiFlex require a KEYLOK USB license dongle to run.  The license dongle, also referred to as a USB key or license key, provides Avanti license units.  Avanti feature availability is controlled by license units.  Only one Avanti license dongle is permitted per hose system.

A full Avanti license provides 175 license units.  An AvantiFlex base license provides 10 license units.  AvantiFlex allows the user to select desired Avanti features without purchasing a full Avanti license.  See the Avanti SPD for more information on product licensing.

FreeAXP does not provide any license units and does not require a license key.
