To install FFmpeg on windows server to make it work with AttachMax, please follow steps below:
1. Download FFmpeg for windows from http://www.attachmax.com/FFmpeg_for_Windows__1.html (5.7MB).
2. Unzip it to some directory (e.g. C:\Program Files\ffmpeg).
3. Open "Servers" tab in AttachMax admin panel and insert FFmpeg path (e.g. C:\Program Files\ffmpeg\ffmpeg.exe).

To use FFmpeg for flv encoding and thumbnails creation, you should select "ffmpeg" as "Video Tool" from "Config" tab in AttachMax admin panel.

Below are links to different FFmpeg and Mencoder Installations, I recommend choosing the option that is best in your situation.
