For several years we have suppressed Flash Player ActiveX from autoupdating by using the mms.cfg file, with the setting "AutoUpdateDisable=1" -- and it has worked without a problem.
With the constant updates of Flash Player for security reasons, we decided several months ago to change the autoupdate setting and allow Flash Player ActiveX to update automatically, without notifying the user, checking every seven days. We changed the mms.cfg file to this:
We are using Windows 7 64-bit, so the mms.cfg file was copied/updated to: C:\Windows\SysWOW64\Macromed\Flash, as well as C:\Windows\System32\Macromed\Flash
The problem we are randomly seeing across our 2500+ computers is a notification that a Flash Player update is available. This is occurring on machines with the mms.cfg file in place.
Does anyone else have this same issue? We were also wondering if the encoding of the file, i.e., ANSI or UTF-8, has any bearing on the effectiveness of this mms.cfg file. Or has a registry setting been updated overriding the mms.cfg?
We believe the file is encoded in UTF-8, but it is difficult to be 100% certain of this.
