Air Update Framework Issue... Help please!

Question

The following code is from the Air Employee Directory example
to which I have added an Update Object, the app installs and
updates with no problem, but as soon as the update is done and it's
time for the app to start, the app just doesn't come up. It was
working fine before I added the update object... Any idea on what I
could be doing wrong?

Answer 1

This was an issue with the Update Framework in AIR SDK 1.5.3, which has been fixed. If you still want to use the ApplicationUpdaterUI, you can replace the swc in Flex SDK 3.6 with an applicationupdater_ui.swc from a newer version of AIR.
Have a look at solution 3 in this post for some details on where to find the applicationupdater_ui.swc and how to replace it.
