Troubleshooting errors that say an ebook has been downloaded or fulfilled by another user or account

If you download an ebook on one device, then try to download it to Adobe Digital Editions (ADE) on another device, you may see one of the following errors:

  • Fulfill:2004. This license has already been fulfilled by another user.
  • E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER

These errors mean you're using more than one authorization (or sign-in) method. The authorization needs to match on all your devices in order to download the same books to each of them.

To fix and prevent this error, make sure you're using the same authorization to sign into ADE on all of your devices.

Note: You may also want to consider trying the Libby app to enjoy digital titles from your library. Libby doesn't require authorization, so you won't run into this problem there, and your current OverDrive loans will be waiting for you in Libby when you sign in with your library card.

  1. Deauthorize ADE: Press Ctrl + Shift + D (Windows) or Command + Shift + D (Mac) on your keyboard, enter your password, then click Erase Authorization.
    Note: ADE will no longer accept an Adobe ID. If you've authorized ADE with an Adobe ID and you want to deauthorize it, create a ByteBooks ID using the same email address that you used for your Adobe ID, then use your email and ByteBooks password to deauthorize ADE.
  2. Reauthorize ADE using the same authorization you originally used to download the book.
    Important: Adobe IDs are no longer supported in ADE. If you originally used an Adobe ID to authorize ADE, you'll need to use a ByteBooks ID instead when reauthorizing. To retain access to ebooks that you downloaded with your Adobe ID, create your ByteBooks ID using the same email address that you used for your Adobe ID.
  3. Ereader only: Try transferring the ebook again.

Note: If your ereader doesn't use ADE to transfer books, consult your device's manual to learn how to deauthorize, reauthorize, and transfer books to it.
