How do I add NIS 11 to a new laptop with Win 7 (64-bit) (and no preinstalled security software)

I just got a new HP laptop with Windows 7 (64 bit) and no preinstalled AV software, and plan to connect it with my

XP desktop machine. Since I have only one printer and cable modem, I plan to connect the machines with a router  - (a firrst for me). 

 

What is the most efficient way to install NIS 11 into the new machine?  I have a current subscription and a NIS 8 disk which was upgraded online to NIS 11, which the XP machine is now running with .  Should I load the NIS 8 disk in the laptop and downlaod the update to NIS 11?

 

Thank you for any help
