I am adding an auto-update feature to my product. So I check
with the server for the latest version and download the appropriate
.air file if a newer version of my application is available. Then I
use the Updater update() function to launch the update process.
This gives me the ugly black window "Installing application"
The question is whether customUpdateUI can possibly help me
eliminate the "ugly black window" and replace it with my own GUI?
From what I puzzled out from the documentation, it seems like
the answer is no. It seems that setting customUpdateUI to true
simply allows my application to launch and intercept the "install"
action when an .air file for my application is launched directly by
the user, which would then allow my application to launch the
updater or not.
