customeUpdateUI for native AIR app installer

Hi,

We have a native installer for a windows and Mac AIR app.

For updates, we use the NativeApplicationUpdater code from:

http://code.google.com/p/nativeapplicationupdater/

After an update has been downloaded and launched, AIR shows a dialong prompting the user to "Replace" or "Cancel"

the update.

I would like to get rid of the dialog as this seems to include a redundant question for the user who chose to update from the first place.

I believe setting the <customUpdateUI> tag at the application decriptor file would hide the dialog, but that causes the update to just launch the existing app. How can I come up with custom logic that will cause the update to actually replace the existing app?

Thanks,

Eilon
