Using Express Install

This topic describes how to detect if the client has the required version of Flash Player to run your Flex application and upgrade the player if necessary. In most cases, the player is an ActiveX control running inside Microsoft Internet Explorer or a plug-in for Netscape-based browsers. You edit the wrapper to include version detection logic, and logic that installs a newer player on the client if necessary. This feature is known as Express Install.

Express Install requires that the client have Flash Player 6.0.65 or later installed on MacOS or Microsoft Windows, and that the browser has JavaScript enabled.
