Files that are installed during a failed installation, or that are left behind when an application is removed, take up hard disk space and can cause problems when you install or run a newer version of the Adobe application.

To delete files from a previous Adobe application installation:

  1. If the Adobe application folder exists, drag it to the Trash. By default, the folders are located in the Applications folder on the hard disk.
  2. Drag the preferences folder to the Trash from the Users/[User]/Library/Preferences folder. (For example, drag the Acrobat folder to the Trash.)
  3. Drag the application PLIST file ([file name]), located in the Users/[User]/Library/Preferences folder, to the Trash. Skip this step if the Adobe application doesn't include a PLIST file.
  4. If you don't have other Adobe applications installed on your computer, drag each of the Adobe folders to the Trash from the following locations:
    • Users/[User]/Library/Application Support
    • Library/Application Support
  5. Empty the Trash. If you receive a message that items are locked and cannot be deleted, press Option as you choose Special > Empty Trash to override the lock.
