Can an ADT-packaged native installer install the AIR runtime in silent mode?

Silent installation of my app works fine when the runtime is installed, as follows:

<path>\MyApp.exe -silent -location "\"C:\Program Files\MyApp\"" -desktopShortcut -programMenu

However, if the runtime is not installed, the invocation does nothing. I've also tried -eulaAccepted.

Is it possible to silently install the app, yet if the runtime is not installed, initiate the runtime install automatically from adobe, preferably with a eula prompt for the user?

Worst case, if the runtime must be bundled in the package, is a sidecar install supported for native installers?

I should note, I cannot package the app as .air. The app uses NativeProcess and bundles an exe.

Thanks.
