Product activation protects you from pirated and counterfeit software. It limits the use of Norton programs to those who bought them legitimately. When you install Norton 360, you must use a unique product key to activate it. You can activate Norton 360 during installation, or after you install it. If you activate it after you install it, you must do so within a limited time, or Norton 360 will not work.

Make sure that your computer is connected to Internet.
