If the user didn't create an account when installing their Norton product or didn't purchase online, they can still create a new Norton Account later. Connect to the Internet and open the installed Norton product. Any installed Norton product will work.
To create a new Norton Account from within your Norton Security product, click onto “Sign In” link in the upper right corner. Click the "Create a Norton account" link in the lower right corner. This will bring up a new "Norton Account Sign Up" window. Enter a valid email address and follow the prompts to create a new account. All information for the Norton product is stored. Follow the steps to store information on other Norton products. Instead of creating a new account, simply log in to the existing account from the other Norton products.
