I have read this tutorial:
but the url of update/description is old:
What is the correct url?
http://www.adobe.com/air/framework/update/description/2.7 and 2.7.1 doesn't works.
Have you checked the tutorial at http://www.leonardofranca.com/index.php/2011/08/22/using-the-update-fr amework-for-adobe-air/
Hum, I don't see the link you mentioned (http://www.adobe.com/air/framework/update/description/1.0) in the article on http://www.adobe.com/devnet/air/ajax/quickstart/articles/update_framew ork.html
If you have questions on the article, you can try posting a comment at the bottom of the article.
