Error #16820 on update

Question

Hi, I'm trying to learn how to use the application updater
framework.
I'am starting from here:
http://www.adobe.com/devnet/air/ajax/quickstart/update_framework.html
I've changed urls in the src/config/update-config.xml, and
when I click on the "check for update" button, the app find a new
version, but when I click on download a receive the error in
subject.
Googling around I found some suggestions, I've tried adding
the mime-type "application/octet-stream" for .air files on my web
server but didn't solved, any suggestion?
Thank you

Answer 1

I did a step ahead and 2 step back. :-(
The previous error was simply caused by a typo in the url of
the new version air file.
Now I'm tryng to do the same thing the sample application
does on my app.
I've included the swf file "applicationupdater_ui.swf", I've
Inserted at the top of the file :
appUpdater = new runtime.air.update.ApplicationUpdaterUI();
appUpdater.configurationFile = new
air.File("app:/defaults/updates-config.xml");
// appUpdater.initialize();
appUpdater = new runtime.air.update.ApplicationUpdaterUI();
appUpdater.configurationFile = new
air.File("app:/defaults/updates-config.xml");
appUpdater.initialize();
If I remove the comment on the third line I got this error:
ReferenceError: Error #1069: Property
mx.resources:IResourceManager::initializeLocaleChain not found on
mx.resources.ResourceManagerImpl and there is no default value.
