Finding Unique NI Computer ID for Activation and Licensing

Updated Feb 25, 2022



  • NI License Manager

  • I am trying to activate my NI Software with a serial number or a license file. Where can I find my computer ID?
  • How do I find the 16-digit computer ID to finish activating the NI Software from the My Products page on I can find my computer's 25-digit product ID from Windows 10, but that doesn't seem to be the information you are looking for.

Note: The computer ID referenced in this Knowledge Base article is a 16-character value that uniquely identifies your computer and is specific to NI Product Activation. The computer ID is typically generated for your device upon the first installation of NI software. Thus, in order to access it, NI recommends installing one of NI's programs first and then following the instructions below.

After installing at least one piece of NI Software, complete the following steps in order to display your computer ID in NI License Manager (NILM):
  1. Open NI License Manager by going to Start » All Programs » National Instruments » NI License Manager.
  2. Select Computer Information or Display Computer Information as shown below.
  3. The computer ID is displayed under the computer's name.

Additional Information

When you activate choosing the manual web or phone methods, the email sent to you will provide the computer ID as part of an information summary. When you activate using the Activation Wizard, all of the necessary information will be gathered for you.

NI License Manager is installed with NI Software that requires licensing. If you do not have NI License Manager after installing your NI Software, then your software does not require activation. If you are installing licensed NI Software, you do not need a separate installer for NI License Manager. 

To download NI License Manager separately, you can follow this KnowledgeBase article: How Do I Install NI License Manager?

With NI License Manager 3.3 or newer, you may programmatically retrieve the computer ID. For more information visit How Do I Programmatically Retrieve My Computer ID?
