    How do I do a clean install of Flash Player?

    chris.campbell Adobe Employee

      In most cases, a clean install is not required when installing Flash Player.  The Flash Player installer will upgrade previous installs without having to uninstall first.  However, if you find you're running into problems or would like to downgrade to a previous version, the following steps and video should help.

       

      Windows

       

       

      If you are viewing this page in Firefox and Flash Player is not working, please click here for an HTML5 version of this video: YouTube HTML5 HD Link

       

      1. Download the current uninstaller
      2. Download Flash Player from Adobe Flash Player Install for all versions
      3. Close all browser windows, and any other application that may use Flash Player (e.g. instant messaging clients, etc) and run the uninstaller
      4. Restart Windows. 

        If you are using Windows 8, 8.1, or 10, do NOT perform steps 4 and 5.

      5. Delete all remaining files (except for the FlashInstall.log file) and folders located in the following directories.  (tip: copy and paste these paths into the path bar in an Explorer window)
        • C:\Windows\system32\Macromed\Flash - do not delete FlashInstall.log file
        • C:\Windows\SysWOW64\Macromed\Flash (if you are using a 64-bit system) - do not delete FlashInstall.log file
        • %appdata%\Adobe\Flash Player
        • %appdata%\Macromedia\Flash Player
      6. Verify that the files “FlashPlayerCPLApp.cpl”, "FlashPlayerApp.exe", and "FlashPlayerInstaller.exe" in C:\Windows\system32\ (for 32-bit systems) or C:\Windows\SysWOW64\ (if you are using a 64-bit system) have been deleted.  If any of these files cannot be deleted, use Unlocker to remove them from your system.
        • Note that you may not see the .exe suffix on FlashPlayerApp.exe and FlashPlayerInstaller.exe, depending on your Explorer settings.
      7. At this point, Flash Player should be fully removed from your system.  Re-install Flash Player using the installer downloaded in step 2.
        • Be sure applications that may use Flash Player and browsers are closed during the installation

       

      Macintosh

      1. Download the appropriate uninstaller from the following page: Uninstall Flash Player | Mac
      2. Download Flash Player from Adobe Flash Player Install for all versions
      3. Close all browser windows and any other application that may use Flash Player (e.g. instant messaging clients, etc), mount and run the uninstaller
      4. Restart OS X
      5. Delete all remaining files and folders locating in the following folders:
        • /Library/Internet Plug-Ins/Flash Player.plugin
        • /Library/Internet Plug-Ins/flashplayer.xpt
        • ~/Library/Preferences/Macromedia/Flash Player/
        • ~/Library/Caches/Adobe/Flash Player/
        • /Library/Application Support/Adobe/Flash Player
      6. At this point, Flash Player should be fully removed from your system.  Re-install Flash Player using the installer downloaded in step 2.
        • Be sure applications that may use Flash Player and browsers are closed during the installation
