Using Express Install in the wrapper
The recommended method of ensuring that Flash Player can run the application on the client is to use Express Install. With Express Install, you can detect when users do not have the latest version of Flash Player, and you can initiate an update process that installs the latest version of the player. The updated Player can be installed from the Adobe website or from a local intranet site. When the installation is complete, users are directed back your website, where they can run your application.
By default, Express Install is enabled in the wrapper generated by Flash Builder.
To enable or disable Express Install in Flash Builder:
When you deploy an application with a wrapper that supports Express Install, you must also deploy the playerProductInstall.swf file. This file is located in the /templates/swfobject directory.
