You're failure most likely is because you didn't register the new purchase at the time you bought it. Since the original version likely was registered, and has expired, they have no way of knowing that you bought a new one.

If you open your Norton and click on Help, you'll find options for registration and for help. I'd suggest going into the registration and entering the new purchase. You will need to "set up an account" and put in a password if you didn't do that previously. Once you've registered the new purchase you shouldn't have a problem, although occasionally a new "subscription date" fails to save properly. Just email them using the link in Norton and it's usually quickly resolved.

When you uninstall a Norton AV version, it leaves a small file that records when your current subscription expires. This is so that you don't lose it if you uninstalled to fix something and reinstall the same version. For a first-time install of a new version, the default (temporary) expiration will be based on the date of installation. When you REGISTER THE PRODUCT with Norton/Symantec the expiration date will be set accurately according to the information you provide at the time of registration.

Installing a new version on a machine where a previous version was used sometimes doesn't reset the expiration date, since the program doesn't know it should change the subscription information. REGISTER the PURCHASE, and all should be well. (And when you set up your account, make a note of username and password for future renewals.)

FOR OTHERS: With current operating systems, some updates can only be installed if the user logged on at the time of update has "Administrator Privilege." If you have an Administrator account on your machine, you should log on as Administrator and run "Live Update" at least monthly, to make sure that nothing that downloaded failed the separate installation step.
