Issue Details

  • My serial number is not activating my NI software.
  • I ordered an upgrade to the latest version of my NI software, but the serial number is not working. 
  • I purchased the LabVIEW Base edition, but my serial number is being rejected for one or more of the packages included with LabVIEW (LabVIEW Application Builder, LabVIEW Report Generation Toolkit, etc.).


If you are having issues activating your NI software, follow the steps below.
  1. Make sure you are activating NI software included under your serial number. For example, a license for the LabVIEW Base edition will not activate the LabVIEW Application Builder add-on.
  2. If you are using your NI User Account to activate the software, make sure you also register your serial number.
  3. Make sure to enter the serial number without any spaces or punctuation.
  4. If the activation using the serial number fails, you can also use 20-digit activation codes to manually activate each NI software license.
    • You can generate the activation codes in the NI Product Activation portal using a device with an internet connection. To create the codes, you will need the Computer ID of the target computer, your serial number, and select the proper version of the NI software that requires activation. For example, if you have LabVIEW 2020 SP1 installed on your computer, you will need to select the same version of the product.
    • If you are having issues using the NI Product Activation portal, contact NI Support and provide the serial number, the Computer ID, and the specific version of the NI software that you trying to activate. 
For example: Serial number MX1234567 Computer ID: XXXX-XXXX-XXXX-XXXX Software: LabVIEW Professional 2020 SP1
