How do I completely delete a Serial Number from a PC?

[jmburns]

We developed a LabVIEW (& TestStand) application for a client on hardware we purchased for them.  We used our Serial Number to activate LabVIEW and TestStand, but now want to strip the Serial Number off so that we don't give our license to our client.  I have Deactivated the license, but if I test it by clicking "Activate," our Serial Number shows up by default.  Is there a way to delete all traces of our Serial Number from the PC, so that our client can't just activate it once we ship them the hardware?

Thanks,
Jason

"...you can simply delete the activated license file. NI license files are stored in the C:\Program Files\National Instruments\Shared\License Manager\Licenses directory. If you delete a license file and then in the future need to activate and use the product again..."

Hope this helps!
