Message: "Invalid Product Key"

This error appears when the product key is typed incorrectly or if the product key is for a different product and version.

Make sure that your key is typed correctly

  • Type your product key again. Be very careful to type it exactly as it appears. Your product key is a combination of alphabetic and numeric characters. It does not contain any special characters.

    If you purchased a boxed product online or at a local retail store, your product key is inside the box or printed on a card in the box.

Common mistakes when entering product key

    • Spaces in the product key will cause an error.

    • Make sure you are entering license information for the specific product you are using. License information for one Norton product is not interchangeable with another Norton product.

      For example, you cannot use the product key for your Norton protection to activate Norton Utilities Premium. You can find the product key for Norton Utilities Premium in the My Subscription page of your account.

    • If you still see a message indicating incorrect or invalid licensing information, verify that you typed the license information exactly as shown.

      Some characters (such as the number 0 and the letter O) can look very similar. Try double-checking the following: the letters O, l (lower-case l), I (capital I); and the numbers 0 (zero) and 1 (one).
