Is it safe to install norton 360 Gold edition on two different computers
I have a HP tower with Windows XP version 5.1 with SP2 and a laptop with Windows Vista Home premium SP2 (32 bit operating system). I want to install Norton 360 Gold Edition but there are a lot of stickers on the Norton 360 pack so I cannot tell if it is safe to load onto both computers. I have heard there are issues with Vista home premium at sp2 level.
Pleas help me as I know little about computers.
