Issue Details

My serial number for my NI software is wrong, or I have a new serial number. I want to use a different serial number for the NI software on my computer without uninstalling and reinstalling software. 


To change your serial number, you'll need to deactivate and then reactivate your software using the new serial number. 

1. Deactivate your software, following the steps in the KB article: Deactivate or Remove License for NI
2. Reactivate your software by following the NI Activation Wizard Walk-Through and using your new, updated, or correct serial number.

The updated serial number will appear in NI License Manager, which can be opened by navigating to Start » Programs » National Instruments » NI License Manager. 

NI License Manager 4.0 and higher:

NI License Manager 3.7 and lower:
