Flash Player Update Instructions

It is recommended that you either use the auto-update mechanism within the product when prompted or the direct download links.  The problem with the auto-update mechanism is that it can take a few days to finally provide the update and up to a week if using the "Notify me to install updates" setting.

Flash Player Auto-Update

The update settings for Flash Player versions 10.3 and above can found in the Advanced tab of the Flash Player Settings Manager.  The locations are as follows:

• Windows: click Start > Settings > Control Panel > Flash Player
• Macintosh: System Preferences (under Other) click Flash Player
• Linux Gnome: System > Preferences > Adobe Flash Player
• Linux KDE: System Settings > Adobe Flash Player

Also note that the Flash Player Settings Manager is where to manage local settings.

Flash Player Direct Download Links

Warning:  Although Adobe suggests downloading the update from the Adobe Flash Player Download Center, that link includes a pre-checked option to install unnecessary extras, such as McAfee Scan Plus or Google Drive.  If you use the download center, uncheck any unnecessary extras.
