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:

• Motherboard
• 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?

1. Launch the Nx Witness Desktop Client
2. Open the Main Menu and select System Administration
3. Select the Licenses tab
4. Select Manual Activation
5. Click on Copy to copy the HWID to your clipboard, and now you can paste it where needed.
