Next Steps

Legacy: NI Software Delivered via Physical Media 

In 2017, NI moved to digital delivery method for software installation media and away from physical media.  

If you’re using software that was previously delivered via physical media (like DVDs or USBs), you can use the Certificate of Ownership to find your serial number. 

The serial number is located on the Certificate of Ownership included in the software kit. If the software kit does not include a Certificate of Ownership, it is possible to find the serial number on the product packing slip or on the shipping label as shown below.

  • Most NI software can be downloaded from as soon as you purchase it, or you can download most software in evaluation mode to try it before you buy it. After you purchase the software, you will receive an email that will ask you to accept access to the software, and NI will link this activated software to your NI user account. 
  • To access your support entitlements, including the ability to download software from, you must register the serial number associated with your software license and/or service program to your NI account. If the download button is disabled, but you believe you’re entitled to that version of software, please ensure that your serial number is registered before calling Support. Reference the article The Download Button is Disabled to learn more.
  • For both Single-Seat Licenses and Volume License Agreements, if you’re unable to find your serial number, or maybe you’re not responsible for using NI License Manager at your company, please reach out to your Software Administrator before calling Support.
  • In some cases, the software may be delivered to you on physical media, or you may request this option when you purchase the item. After the software kit arrives, the serial number included in it can be entered in NI License Manager to permanently activate the software. 

  • NI Community edition software, like LabVIEW Community edition, does not use serial numbers to activate.
