How do I ADD my NEW COMPUTER to the curent account?

Norton just renewed my NIS account, so I suppose it was for NIS'07.  But it is valid for three computers.  I have a new computer with no trial version on it.  So how do I add my new laptop to the account, how do I get it installed and activated, etc?

 

Thanks!
