Adobe platform evangelist Serge Jespers released on his blog a valuable AIR 2 "alpha" application that allows you to quickly build native application installers for your AIR 2 applications. Native installers are required if you are building an AIR 2 application that takes advantage of the new extensibility options available from the native process API. This tool simplifies the process of creating a native installer since you do not need to construct a command line statement and can, instead, use a graphical, wizard-like interface.
Serge shared instructions on how to setup the application on his blog as well. The application is currently considered in an "alpha" and, if you have feedback on bugs or feature requests, please be sure to leave Serge a comment.
