Flare is a freeware ActionScript decompiler

http://www.swftools.com/tool-details.php?tool=7775954268

"The Windows version works as an Internet Explorer extension: after installation right-click on any SWF file in Windows Explorer and choose Decompile from context menu. Flare will decompile the swf to a simple text file. You can then open it with your favorite text editor. If Flare encounters problems during decompilation, it will display some warnings. "

edit: installed, rebooted even: nothing!? (win xp home)
anyone gets this to work?
