The License Update Utility is used to update Avanti primary and backup USB license dongles.  The utility applies an update file or update pass-phrase to the dongle.  Each update is unique to a single dongle.

An Avanti license can be updated on any system capable of supporting the software and equipped with a USB port, including a laptop.  Simply install the Avanti software (no dongle required for installation), plug in the dongle, and apply the update.
