IT Administration | Configure Flash Player auto-update notification

Quelle: Adobe Knowledgebase

Adobe Flash Player supports notification of software updates by periodically checking for new versions of the player on the Adobe website. Flash Player never runs in the background to perform the auto-update check. The check is only performed when the player is loaded to view Flash content, typically in the browser. By default, the check only occurs if it has been at least seven days since the last time it checked for updates. IT administrators can customize the update notification behavior for their users. The auto-update notification settings can be configured in two ways: user settings or an administrator deployed configuration file.

User configuration of auto-update notification

Users can set the frequency of the checks or disable auto-update notification by using the Flash Player Settings Manager. These user-configured auto-update settings are stored in a local shared object on the users machine.

To learn how individual users can disable auto-update, see How to disable auto-update notification in Flash Player.

Administrator configuration of auto-update notification

Administrators can configure auto-update notification settings by deploying a file named mms.cfg. The mms.cfg file is intended for configuration by an IT administrator and is stored on the user’s computer. Flash Player installation does not create the file. You can use third-party administration tools, such as Microsoft System Management Server, to replicate the configuration file to the user’s desktop.

The mms.cfg file is a UTF-8 text file. The format of the mms.cfg file is a series of name=value pairs separated by carriage returns. If a parameter is not set in the file, Flash Player assumes the default value. When set, values in this file override the user-configured settings stored in a per-user local shared object.

Note: Settings in mms.cfg override the users settings and users cannot change it through Settings Manager. Settings Manager, as viewed by the user, doesn’t reflect configuration settings set by mms.cfg.

If you are deploying Flash Player 8 or later, store the mms.cfg file in the following location depending on the operating system:

  • Windows NT, 2000— C:\WINNT\System32\Macromed\Flash
  • Windows XP, Vista —C:\WINDOWS\System32\Macromed\Flash
  • Windows 95, 98, or ME–C:\Windows\System\Macromed\Flash
  • Windows 64-bit — C:\Windows\SysWOW64
  • Macintosh–\Application Support\Macromedia

For player versions earlier than Flash Player 8, store the mms.cfg file in the following location depending on the operating system:

  • Windows NT, 2K–C:\WINNT\System32
  • Windows XP, Vista— C:\WINDOWS\System32
  • Windows 95, 98, or ME–C:\Windows\System
  • Windows 64-bit — C:\Windows\SysWOW64
  • Macintosh— \Application Support\Macromedia

Note: Flash Player 8 and later versions can read mms.cfg from either the new or old location. If mms.cfg exists in both locations, Flash Player 8 reads settings from the new location.

The following table describes settings in the mms.cfg file:

 

Parameter Default Description
AutoUpdateDisable 0 0 allows auto-update based on user settings.
1 disables auto-update.
AutoUpdateInterval <0 (or absent) Takes a numeric value.

<0 (or absent) uses value from player settings.
0 checks for updates every time the player launches.
>0 specifies the minimum number of days between check for updates.

Disable auto-update notification
  1. Create or open the mms.cfg file in a text editor.
  2. Add the following auto-update setting:
    AutoUpdateDisable=1
  3. Save the mms.cfg file with UTF-8 encoding in the correct system location for the user’s operating system.
  4. Close and restart Flash Player or the browser in which Flash Player is running for the new setting to take effect.
Test auto-update notification settings

Administrators can verify the mms.cfg configuration has disabled auto-update by using a packet sniffer with the following test:

  1. In mms.cfg, set AutoUpdateDisable=0 to allow auto-update. Verify that auto-update is enabled in Settings Manager.
  2. Add the auto-update setting:
    AutoUpdateInterval=0
    With this setting, Flash Player requests the version file every time it starts and the request appears in the network request traffic.
  3. Open a web page with Flash content to start Flash Player. A simple page with a single piece of Flash content is best, to minimize the network traffic in the packet sniffer log. The packet sniffer shows the auto-update request traffic to http://fpdownload.macromedia.com/
    Note: Avoid using www.macromedia.com as your test page, since the auto-update request is lost in the other file requests.
  4. Set the AutoUpdateDisable to 1 to disable auto-update notification.
  5. Open a web page with Flash content to start Flash Player. There is no version file request traffic.
