Missing Files needed to make demos usable for editing

[cmv950]

Hey guys, I know this may sound like a stupid question but im new to the whole making videos from recorded demos thing. I know that you need to have the ffmpeg4mxsim file which converts the demos to video form which can then be put in movie maker, but it isn't working right because I don't have the other files that you need to make it work. I know I was on a form the other day which showed like three other things that needed to be downloaded with it to make it work, but I had to get somewhere and was already late so I ended up only downloading the ffmpeg4mxsim file and didn't get the others. I haven't been able to find the page since and need to in order to make the video files I found be usable in movie maker. If anyone could tell me what I need besides the original ffmpeg4mxsim file to make it work please let me know or direct me to the page that I found that had them on it. Thanks! (No smartass or retorical responses please, im new to this whole thing so I need all the help I can get.)
