Node-locked to a FlexNet ID Dongle
To move a license between different systems, it can be locked to a FlexNet ID dongle (a dongle that connects to a parallel or USB port). You can move this license between systems by installing a copy of the license file with a hostid set to the FLEXID of the dongle on each system and moving the dongle from one system to another. Since the license is tied to the dongle, only the system with the dongle can use the license.
FlexNet ID dongles are made available by your software publisher. Your software publisher can also provide you with an installer that installs drivers for all FlexNet ID dongles.
