Hardware Bound License
A Hardware Bound License is tied to the hardware of the server where you installed LogicalDOC in.
Licenses of this type are associated with a specific device upon activation and do not work on other computers.
To check if you are using a license bound to a specific hardware, open the license page and check if the System ID parameter is not empty.

License Unbind
If something changes in your hardware or main software components, or simply you move your installation to another server, the license gets invalidated thus you have to unbind the license and activate it again.
