To use, extract the .exe somewhere, open a cmd.exe and cd your way to where you extracted the binaries, ie: ‘cd C:\freestyle\befree-win32′ if you extracted to C:\freestyle. Then set the FREESTYLE_BLENDER_DIR as follows:

set FREESTYLE_BLENDER_DIR=”C:\freestyle\befree-win32\.blender\scripts”

After that start blender: blender.exe and choose Freestyle as renderer in the render settings. A new panel in render settings appears, here you can choose different freestyle module to render with. Hit F12 and enjoy!
