Disable AIR Framework Autoupdate
Programmatically Disable AIR Framework Autoupdate from Air Application
In a previous post you can find how to enable/disable Adobe AIR Framework Autoupdate using the Adobe AIR Manager tool.
We had the problem that we wanted to disable Adobe Air Framework from our AIR Application but we never found a way to do this even if the Adobe AIR Manager tool is a air based file. But a few days ago without any doubt what it must be we found a file inside the “C:\Documents and Settings\[user]\Application Data\Adobe\AIR\” (win XP) named “updateDisabled”. After enabling the Adobe AIR Framework Autoupdate the file was erased right away.
Then we found the all the magic of setting Adobe AIR Framework Autoupdate value it the presence of a specific file inside a specific folder. Nothing more.. no registry, no encrypted settings files or else.
We took the time and created a simple AS3 class that you can use for Manually Enable/Disable AIR Framework Autoupdate from your Abobe AIR application.
You can download the class from here: SettingsManager.zip or just browse the class code:
