Typically AIR developers will all want to take advantage of the Update capability, but in it’s original form requires some work. Rich Tretola’s UpdateManager did the job, but I wanted more programmatic control, interception of events and a slightly different UI work-flow, and set about creating my own.  Just as that phase of the work is completed, I find Adobe’s Update Framework on labs which although beta, does a much better job. I wish it was there a week ago.

Also, I just took the opportunity to update to AIR 1.1. Unfortunately updating Flex to use the new AIR is a little messy (in that it requires manually copying some files rather than running an installer) and means moving to the 3.0.2 stable build of the Flex SDK. However it is not difficult and the instructions to follow are here.
