Locate the directory installDirectory/Flex Builder 2/Player/debug.
In a default Windows installation this directory would be C:/Program Files/Adobe/Flex Builder 2/Player/debug.
To install Flash Debug Player for Internet Explorer, run the program Install Flash Player 9 AX.exe. For other versions of web browsers, run the program Install Flash Player 9.exe.
In rare instances, you might run the appropriate installer and still get the message that you don't have the debug version of the player. In this case, uninstall the version you currently have by using the information located at this URL: www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_1415.
