I have Norton Antvirus 2002 with a supscription(will last about 7 more months). I have a crack for Norton 2004. Do I have to download and install norton 2004 then put in crack or is there some way i can just upgrade with the crack i have? Also what will happen to my current subscription (for norton 2002) if i get norton 2004? FYI I saw a norton subscription crack on a site but im not sure if it will work.
