Adobe® AIR™ allows you to run AIR applications on the desktop. You can install the runtime in the following ways:

• By installing the runtime separately (without also installing an AIR application)
• By installing an AIR application for the first time (you are prompted to also install the runtime)
• By setting up an AIR development environment such as the AIR SDK, Adobe® Flex™ Builder™ 3, or the Adobe Flex™ 3 SDK (which includes the AIR command line development tools)

The runtime only needs to be installed once per computer.
