Flash Player information

If Flash Player is installed on your computer, the following box displays the version of Flash Player and your operating system. If Flash Player is not installed, an error message appears.

 

Issue

Flash Player installation was not successful.

Solution: Download and run the uninstaller

1. Determine your Mac OS version 

  1. Click the Apple icon in the upper-left corner of your screen.
  2. Choose About This Mac.

    The Mac OS version appears in the About This Mac dialog.


2. Run the uninstaller applicable to your Mac OS version

Note:

Beginning with Flash Player 11.5, uninstalling the Flash Player resets the AutoUpdateDisable and SilentAutoUpdateEnable settings in mms.cfg to their default values, which are:

  • AutoUpdateDisable=0
  • SilentAutoUpdateEnable=0

If you are running the Flash Player uninstaller as part of your deployment process, redeploy any custom changes to either AutoUpdateDisable or SilentAutoUpdateEnable.

Run the uninstaller on Mac OS X 10.4 and later (Tiger, Leopard, Snow Leopard, Mountain Lion, and Mavericks)

  1. Download the Adobe Flash Player uninstaller:

    The uninstaller is downloaded to the Downloads folder of your browser by default.

  2. In Safari, choose Window > Downloads.

    If you are using Mac OS X 10.7 (Lion), click the Downloads icon displayed on the browser.

    Select Window, Downloads

    In Mozilla, choose Tools > Downloads.

  3. Double-click the uninstaller in the Downloads window to open it.

    Note: If the Flash Player installer window does not appear, choose Go > Desktop in the Finder. Scroll down to the Devices section and click Uninstall Flash Player.

  4. Double-click the Uninstaller icon in the window to run the uninstaller. If you see a message asking if you want to open the uninstaller file, click Open.

  5. When the uninstaller starts, click Uninstall.
  6. Bookmark or print this page so that you can use the rest of these instructions after you close your browser.
  7. To close all browsers, either click the browser name in the Uninstaller dialog, or close each browser manually and then click Retry.

    Note: Do not click Quit in the Uninstaller window. It stops the uninstallation process.

  8. After you close the browsers, the uninstaller continues automatically until the uninstallation is complete. When you see the message notifying you that the uninstallation succeeded, click Done.



  9. Delete the following directories:

    • <home directory>/Library/Preferences/Macromedia/Flash\ Player
    • <home directory>/Library/Caches/Adobe/Flash\ Player

Otherwise, the uninstaller cannot finish (even though it appears to finish).

    Once the uninstaller finishes, the window closes automatically.
