Renewing a license

Hello

 

My license is about to run out on my desktop computer but I notice the license for my laptop does not run out until November this year and I can still use it on 1 more PC.

 

My idea was to uninstall Norton from the desktop and download the one I have on my laptop from the Norton server.

 

Is this the correct way of doing it or can I simply enter the laptop key on the desktop?

 

Suggestions would be most welcome.

 

Kind regards

Alan
