This guide applies to the purchase of new Sibelius Ultimate and Sibelius (formerly “First”) and to all updates to single-user licenses.
It does not apply if you have purchased a new Academic edition or a multi-user license -
see the instructions here for Sibelius Academic.
The guide was updated on November 25, 2019. Avid changes the procedures from time to time, and we try to update the guide as much as possible, but if you find something is wrong or unclear, so feel free to write it to us.

Sibelius is delivered as a serial number / download code, which you have received in your order confirmation from the webshop or sent in a separate email.
The code might look like this: SIBXX226-XX2949458-X932464.
You follow this link:, which takes you to the Avid account page, where you can login to your existing account on the left and create a new account on the right:

If you do not remember if you have had an account before, you can enter your email address and select “Forgot Password”. Then you will either be notified how to reset your password, or that your email address is not found at Avid, and you will then need to create a new account on the right side of the image.
Once the account is created, you will be taken to the activation page:

Here you enter the long code that starts with SIB-… Along the way, you may be asked to verify your address information etc. If you have purchased an update, you will be asked to enter the old serial number or System ID.
Then you see this picture (depending on which AVID products you otherwise own):

Important! To see details about your product, now click on the blue “VIEW Software Download Links”.
Then the list of software, accessories and links unfolds:

Now you can download the latest Sibelius for Mac and Windows as well as the Sibelius Sounds audio library, an update to Sibelius Sounds, PhotoScore Lite and AudioScore Lite. Your download code is now used and is no longer valid as you have everything you need lying around in your Avid account.

If you get lost or click on something wrong, you can always return to the main page of the account by clicking on My Account at the top right.

From the front of the account, you can maneuver on to the activation page “Register Software With Code” (if you have not been there yet) or to View My Products, where you can again press “VIEW” (see above) to get to your downloads , which otherwise remains on the account, but is automatically replaced by newer versions as long as your update plan is active, ie up to 12 months after the first activation. On the front page of the account you can also see when your update plan expires. Remember to renew before the expiration date, and remember to buy here on (and never on!), So we still have the resources to help and guide.

Sibelius Activation

The first time you open your new Sibelius, you will be prompted to activate the application.
