Install and activate Norton 360 Deluxe

With your order you receive a product key for Norton 360 Deluxe. The program comes from Norton. This guide takes you from the key in your email to Norton running on Windows.

What you received

Your order confirmation email contains a 25-character product key for Norton 360 Deluxe. The same key is in your Lizensa account under My Library.

• No installer comes with the order. Norton provides the download once you have entered the key.
• You need a Norton account. Norton ties the subscription to an account. You can create one while you enter the key, or add the key to an account you already have.
• Keep the key private. Do not post it online or pass it on.

Norton lists these systems for its device security app: Windows 11 or 10 (not in S mode), Windows 8 and 8.1, and Windows 7 with Service Pack 1 or later. Windows 7 needs SHA2 support. If your PC runs Windows in S mode, Norton asks you to install from the Microsoft Store instead.

Get the software

Norton's route for a key that does not come from Norton's own shop starts at its setup page.

1. Go to norton.com/setup.
2. Enter your product key and select Next.
3. Enter a valid email address and select Next.
4. Sign in if Norton asks. You can request a code by email, or enter your password and select Sign In. If you have no account, select Create an account and finish the sign-up.
5. Norton may ask for payment details for automatic renewal and then ask you to select Activate Subscription or Activate Automatic Renewal. Read what is offered before you confirm. Automatic renewal is Norton's service, not ours.
6. Read the License and Services Agreement and select Agree and Download.
7. Run or save the downloader file, as your browser allows, and follow the prompts.

Install

1. After the download finishes, open the downloader file. In many browsers, press Ctrl+J to open the Downloads window.
2. If Windows asks whether the app may make changes, select Continue or Yes.
3. Select Install Norton 360.
4. Wait while Norton installs. It activates itself as part of the installation.

Activate

If you followed the steps above, there is nothing more to do: the key is already redeemed. Use this route only if Norton is already installed and shows that it is not activated.

1. Open Norton.
2. Select the profile icon at the top right of the main window.
3. Select Serial Number. Enter the 25-character key and select Next.

Your PC must be online for activation to finish.

Check it worked

1. Open Norton. It should no longer ask you to activate.
2. Sign in at my.norton.com with your Norton account. Your subscription is listed there, and you can download Norton again from the dashboard.

If something goes wrong

Norton says "Invalid Product Key". Check the key against your email, character by character. Copy and paste it. If it still fails, contact us with your order number.

Norton says "No License Available". The subscription in the account has expired, or you signed in to an account that has no valid subscription. Sign in with the account you used for the key.

Your PC runs Windows in S mode. Choose Get it from Microsoft if Norton offers it and install Norton from the Microsoft Store.

You cannot finish activation. Check the internet connection. Norton needs it for the last step.

You want Norton on another PC. Sign in to my.norton.com, open your subscription and download Norton there.
