Flash Player Update Instructions

Warning:  Although Adobe suggests downloading the update from the Adobe Flash Player Download Center, that link includes a pre-checked option to install Google Drive.

It is recommended that you either use the auto-update mechanism within the product when prompted, or my preference, the direct download links.

• Non-IE (Opera, Firefox, Etc.):  http://download.macromedia.com/get/flashplayer/current/licensing/win/install_flash_player_11_plugin.exe
   
• Windows XP, Vista and 7:
  Flash Player For Internet Explorer 7, 8, 9, 10:  http://download.macromedia.com/get/flashplayer/current/licensing/win/install_flash_player_11_active_x.exe

• Flash Player Uninstaller:  http://download.macromedia.com/get/flashplayer/current/support/uninstall_flash_player.exe

Notes:

• If you use the Adobe Flash Player Download Center, be careful to uncheck any optional downloads that you do not want.  Any pre-checked option is not needed for the Flash Player update.
• Uncheck any toolbar offered with Adobe products if not wanted.
• If you use alternate browsers, it is necessary to install the update for both Internet Explorer as well as the update for alternate browsers.
• The separate 32-bit and 64-bit uninstallers have been replaced with a single uninstaller.

Adobe Flash Player for Android

The latest version for Adobe Flash Player for Android is available by downloading it from the Android Marketplace by browsing to it on a mobile phone.   

Verify Installation

To verify the Adobe Flash Player version number installed on your computer, go to the About Flash Player page, or right-click on content running in Flash Player and select "About Adobe Flash Player" from the menu. 

Do this for each browser installed on your computer.

To verify the version of Adobe Flash Player for Android, go to Settings > Applications > Manage Applications > Adobe Flash Player x.x.

Adobe Shockwave Player

Adobe has released a security update for Adobe Shockwave Player 12.0.3.133 and earlier versions on the Windows and Macintosh operating systems.

This update addresses vulnerabilities that could allow an attacker, who successfully exploits these vulnerabilities, to run malicious code on the affected system.

Although I have yet to need Shockwave Player on this computer, there are still many people who use it.  If you have Shockwave Player installed, please update to the latest version.

Release date: September 10, 2013
Vulnerability identifier: APSB13-23

CVE number: CVE-2013-3359 and CVE-2013-3360
Platform: Windows and Macintosh

The newest version  12.0.4.144 is available here: http://get.adobe.com/shockwave/.  As usual, watch for any pre-checked add-ons not needed for the update.
