Sometimes a "file association" error occurs in Windows. What this means is that Adobe Digital Editions (ADE) is not set to open ACSM files, which are used to download eBooks. If you can't open eBooks in ADE, follow the appropriate steps below.
Associate ACSM files to ADE in Windows 8, 7, or Vista
- Windows 7 or Vista: Click Start, and type "Default Programs" into the search box and press Enter.
Windows 8: Use the Search charm to search for "Default Programs." Charms pop out of the right edge of your screen.
- Click Associate a file type or protocol with a program.
- Scroll down, and select the ACSM file type.
- The extension should be set to "Adobe Digital Editions" (under "Current Default"). If this is not the case, click Change program . . .
- Windows 7 and Vista: Click the Browse button and select DigitalEditions from the following location:
Windows 8: Scroll to the bottom of the pop-up window and click Look for another app on this PC. Then, select DigitalEditions from one of these locations:
- 64-bit Systems: C:\Program Files (x86)\Adobe\Adobe Digital Editions
- 32-bit Systems: C:\Program Files\Adobe\Adobe Digital Editions
Note: You can find which system type you have by going to Start > Control Panel > System. Look under "System Type." Or, in Windows 8, search for System using the search charm.
- Click the OK button to save the changes.

- I scrolled down but ACSM is not there.
- Hi John,
ACSM should only be there if you've installed an application that can handle .acsm files or if you've tried to open an .acsm file and told it to use always use an existing application. It's also possible that the association existed in the past but was deleted somehow.
If your computer simply says it does not know what to do with .acsm files then you should get a prompt to find a program either online, or in the store, or already existing on this computer (the wording, options, and whether they are shown right away or you have to follow a "more options" link vary by Windows version). If you already have Adobe Digital Editions installed, then use the option that corresponds with "find existing program already installed" and then browse to the DigitalEditions (or DigitalEditions.exe) file in \program files\adobe\adobe digital editions\ (or with the (x86) if present).
For exact instructions on how to make the change on your version of Windows try performing a Google search for "tell windows 10 to alway open extention using specific program" or similar. Replace the 10 in the search with your version of windows.
