Expiring Activation Codes Appear as Invalid in NI License Manager

Updated May 21, 2019

Software

  • NI License Manager

Issue Details

I received temporary/expiring activation codes for my National Instruments software. When I enter these codes into NI License Manager (NILM), I receive an error message:
  • The activation code is invalid.

Solution

Expiring Activation codes require NI License Manager version 3.7 or higher. Earlier versions will only recognize permanent activation codes, so temporary codes show up as invalid.

Downloading the latest version of NI License Manager should fix the error.

Additional Information

NI License Manager 3.7 is only compatible with Windows XP SP3 and later. Earlier versions of Windows cannot use expiring activation codes to evaluate NI software.
