To verify if a vulnerable version of Adobe Download Manager is installed, and to uninstall Adobe Download Manager if necessary, please follow the directions below:

Windows:

  1. Browse to the following location:
    <volume>:\Program Files\Common Files\Adobe\ESD\
  2. Locate the file named AdobeDownloadManager.exe. If the directory or file do not exist, no further action is required.
  3. Right-click on the AdobeDownloadManager.exe file and select Properties.
  4. Click on the Version tab of the Properties dialog box.
  5. If the version is 2.1.x or lower, uninstall using the uninstaller provided here.

Macintosh:

  1. Browse to the following location (be sure to check all active volumes):
    /Volumes/<volume>:/Applications/Utilities/
  2. Locate the file named ‘Adobe Download Manager’ or ‘Adobe Reader Download Manager’. If the file does not exist, no further action is required.
  3. Click on the file and select File>Get Info, or Control-click and select Get Info.
  4. If the version is 2.1.x or lower, uninstall using the uninstaller provided here. Users of Macintosh Classic OS can use the uninstaller provided here.

    NOTE: If the uninstall fails, it may be due to permission issues with the install directory. Dragging the file in /Applications/Utilities/ named ‘Adobe Download Manager’ or ‘Adobe Reader Download Manager’ to the Trash and authenticating as prompted will also uninstall the software.
