Are you using any proxy server? Please go to C:\Windows\SysWOW64\Macromed\Flash path delete FlashInstall.log and open mms.cfg file and add SilentAutoUpdateVerboseLogging=1. In the same path you will find FlashPlayerUpdateService.exe. Run the service. Share the FlashInstall.log file created. To share the same you can go through How to share a document. Post a link to the shared file here.
Flash Player is failing to update because the (new) file is failing to download. The specific error in the log file is:
2017-3-27+13-11-43.54 [error] 1214 12002
1214 = Error has occurred when downloading installer
12002 = Windows error code - ERROR_INTERNET_TIMEOUT The request has timed out.
Possibly due to proxy server or firewall rules. The machines that are failing need to be able to allow the new version file to be downloaded in the background.
Could you please let me know what URL and Port it establish to download the Content , so that I can check if any firewall or any policy is blocking not to download the files through Internet automatically.
But when we manually invoke we able to download the Files without issues and Moreover we have acrobat auto update enabled and I see its working very Fine.
I sent you a private message.
As for Acrobat auto update working, Acrobat doesn't use the same update mechanism as Flash Player. I can't speak as to why it works for Acrobat, but is not working for Flash Player.
You may also consider hosting the background update resources locally within your organization. More information on Background Update resources see the section 'Background updates from an internal server' in the Flash Player Administrator Guide.
Thanks for your swift reply ,
Looks its the proxy of our environment which is blocking the traffic and causing this issue . Will let you know in case we still face any issues.
I suspect the issue you posted at Flash Popup Issue is related to this issue. If you're firewall rules are blocking the Background Update Service then the system will not be updated via Background Update Service. Technically a system that is opted into Background Update is still opted into Notification Updates.
Background Updates checks for an update once per day, using the Background Update Service). If an update is found it's downloaded and installed silently in the background.
Notification Updates checks for an update once every 7 days (Flash Player makes this check, not a Service). If an update is found a RunOnce registry entry is created, which displays the Notification Update dialog window your clients are seeing.
If the firewall rules are blocking the Background Update check, then your clients are getting the Notification Update notification announcing a new version is available.
