I was under the impression that installing AIR applications silently require magical versions of the installers which are only acquired after signing a redistribution license, but it appears that silent install is possible with the standard/public installers.
An application can be installed silently like this:
airappinstaller.exe -silent "full/path/to/air/file"
The actual runtime can also be installed silently, again this is the standard version available from http://get.adobe.com/air/
AdobeAIRInstaller.exe -silent
Should this be possible or have Adobe made a booboo?
