Sometimes a "file association" error occurs on your computer, which prevents Adobe Digital Editions (ADE) from opening downloaded eBooks. If you're having trouble opening eBooks in ADE, try the steps below to make sure that your computer opens ACSM files (which are used to download eBooks) in Adobe Digital Editions.

Note: If you're using the Firefox browser, you'll also need to change the ACSM file association there (to make sure Firefox opens ACSM files with the correct program).
