If you are working with National Instruments (NI) software—whether it’s LabVIEW, TestStand, or NI-DAQmx—you know that managing licenses can sometimes feel more complicated than writing the actual test code. The NI License Activator (specifically the 2021 version) remains a staple tool for volume license administrators and individual users who need to activate, deactivate, or repair software entitlements offline.
