After activation, every Nx Witness license is locked to the Hardware ID (HWID) of the computing device upon which it is installed. This article describes what the HWID is and where to locate it for license troubleshooting purposes.
What Is a Hardware ID in Nx Witness?
The HWID is a unique 34-digit identifier (example: 03000102030405060708090a0b0c0d0e0f) generated when the Nx Witness Server is installed on a Windows, Ubuntu Linux, or ARM device. The HWID is based on a combination of software and hardware of the computing device upon which Nx Witness is installed.
The following items are used to generate a unique HWID for each computer upon which Nx Witness is installed:
- MAC Address
After installing Nx Witness on a server, any modification in the components above will result in a change of HWID and an invalidation of licenses attached to that device.
How Do I Find My HWID?
Launch the Nx Witness Desktop Client
Open the Main Menu and select System Administration
Select the Licenses tab
Highlight a License installed on your target Server
Select a license attached to the server for which you want to see the HWID and License Details.
Click on the Details button.
You should now see a dialog that shows the License Type, License Key, and Hardware ID.
To copy the license information (including the HWID), press the Copy to Clipboard button.
