we´re a company with about 2000 Win10 Clients and different Browsers like Firefox ESR and Google Chrome for work (all in latest Versions).
Like (hopely) all Companies, we are using different Groups for testing new Software like Flash Player. Therefore it takes about one Week for testing.
The user gets a message like "You´re using an old version, please download the latest version HERE":
The Download is blocked by our Firewall, the User has no rights to install some Software. Every time Adobe releases a new version of the Flash Player, hundreds of users are calling our service desk and reports a message like above.
Do you know another method or e.g. some mms.cfg option to solve this issue?
Thanks in advance!
You can block Flash Player from checking for an update, but you can't block content from checking for an update as that is written into the content by the content developer. Only the content provider can modify their content to not check for Flash Player.
The vast majority (if not all) Flash Player detection scripts don't use the masterversion.xml file. That file was a recent addition and the most common Flash detection script (SWFObject) used by content providers doesn't use this file.
To disable Flash Player from checking for an update, add AutoUpdateDisable=1 to the mms.cfg file saved at C:\Windows\SysWOW64\Macromed\Flash (64-bit OS) and C:\Windows\System32\Macromed\Flash (32-bit OS)
For Chrome, Google embeds Flash Player in Chrome and all Flash Player updates for Chrome are released by Google, not Adobe. Google does block Flash by default, so this is most likely the reason you are getting the message you're seeing on Chrome. This message is also controlled by the content developer. In you're case, the content developer has a message that the user has an older version of Flash. On Chrome, this is most likely incorrect as Google keeps Flash Player up-do-date, and the reason for the message is because Flash is blocked by default on Chrome.
You can try to whitelist the sites in Chrome by going to chrome://settings/content/flash?search=flash and adding the website that have Flash to always allow Flash. This may or may not work.
