Hi Paul,
Do you use National Instruments Volume License Manager (VLM)?
If not and this is a simple activation question, you will be okay to simply reactivate your copy of LabVIEW on your new computer using the same serial number. With a named user license you can activate the same license on up to three computers at a time. If you uninstall from one of these computers you are free to install on a different computer -- we do keep track of how many times a serial number is activated, but understand that sometimes users will move an installation to another computer, or may have to reactivate due to hard drive crashes, etc. Hope this helps!
