My National Instruments Activation Code Does Not Work

Updated Oct 25, 2018

Reported In


  • LabVIEW Base
  • LabVIEW Full
  • LabVIEW Professional

Issue Details

This issue could occur in different situations:
  • I completed the activation process using my serial number and I did not receive an activation code.
  • After entering my serial number I receive an error that says that it was unable to connect to the Internet, even though I have Internet connection. 
  • I did receive a 20-digit activation code but my software remains in "Evaluation" or "Unlicensed".
  • I am trying to activate my software using a 20-digit activation code, but it says it is invalid or fails to activate my software.


Activation codes are generated based upon the combination of product, serial number, version, and computer ID, and will only work for the specified system. 

If you run into trouble using an activation code, ensure the correct information was entered. Verify:
  1. Computer ID
  2. Product - for example, LabVIEW and LabVIEW Remote Panels are not the same.
  3. Version - for example, LabVIEW 2012 Professional, LabVIEW 2012 Full, LabVIEW 2012 Professional SP1 will all require different activation codes.
  4. Serial Number - ensure that the serial number you enter is for the exact product you are activating.
  5. NI License Manager 3.7 or above installed. There have been problems with activation codes and serial numbers not working for versions before 3.7.
If possible, use the Automatic activation method. This method doesn't require any manual data entry except for the serial number. This method does require an internet connection on the computer trying to activate. It will automatically install the activation code if the serial number matches the product.

For more information, please see the Activation FAQ.  If your activation still fails and you have verified your information, you can contact National Instruments.

Additional Information

The most direct way to determine what software is and isn't activated is to open up NI License Manager on your local machine and confirm that the icons in your Local Licenses tab are what you expect. You can activate and deactivate software from this page by right-clicking on any license entry.
