The AIR environmentAdobe AIR must be installed for a user to install and run AIR applications. Each AIR application runs in a separate process. AIR applications are written using tools and languages used in web development, including HTML, Ajax, Flex, and Flash. Adobe AIR enables developers to use these to deploy rich Internet applications that run on the desktop. AIR runtime files and locationsAdobe AIR is installed to the following locations:
Adobe AIR is a runtime in which AIR applications run. It also includes the AIR application installer, used to install AIR applications. For information on installing and removing Adobe AIR, see Adobe AIR installation. Data formats usedAIR applications are deployed as AIR files (files with the .air filename extension). An AIR file is an installer file for a specific AIR application. When the user launches an AIR file (for example, by double-clicking the AIR file), the runtime opens the AIR application installer, which provides a graphical user interface for installing the application. The application installer displays the identity of the application’s developer (based on the developer’s certificate), if known. The installed AIR application is added to a subdirectory of the standard application directory (for example, a subdirectory of C:\Program Files on Windows and /Applications on Mac OS). The installed application directory includes the following:
AIR applications can access the local file system, and they can write files (of any type) to directories for which the user has write privilege. Each AIR application is signed, and an installed application cannot run if any files in the installed application directory do not match the application’s signature. Network protocols usedAdobe AIR applications can use the following network protocols:
