I recently upgraded from XP to Windows 7 and have had to re-install a few things so I figured I would post the instructions as I set them up. This is about setting up the extremely very valuable tool for every Flash developer that is Flash Tracer. But it CAN be a pain to setup with multiple versions scattered around the web, various instructions on different blogs, and quite often important tips buried in the comments of said blogs. Hopefully this can help you setup Flash Tracer without a lot of effort.
I am using Firefox 3.5.5, on Windows 7, with the Flash Player 10,0,32,18 debug installed.
