Launch configurations are used to both run and debug applications. Flex Builder provides a default launch configuration for Flex and ActionScript 3.0 applications. When you first run or debug a project, a project-specific launch configuration is created. You can edit the launch configuration to change the default main application file or to modify the default launch path to run or debug in the Flash desktop player rather than in a web browser.
