I downloaded and installed: http://fpdownload.macromedia.com/pub/flashplayer/updaters/11/flashplay er_11_ax_debug_32bit.exe
I am running IE 9.
When I hit f11 to debug after switching to IE, I get a window saying:
Installed Adobe Flash Player is Not a Debugger
Flash Builder cannot locate the required debugger version of Adobe Flash Player. You might need to install the debugger version of the Flash Player or reinstall Flash Builder.
Do you want to debug with the current version?
Download and Install Flash player debugger listed here for different browser http://www.adobe.com/support/flashplayer/downloads.html
and set that browser as default bowser for your Flash Builder (Windows -> Preferences -> General -> Web Browser)
