  1. It installed fine for me. I ran the program, hoping it would convert MP4 youtube videos into MP3 files for my audio player. No can do. It only converts audio files to audio files.

  2. Format Junkie is licensed under GNU GPL v3, so it IS NOT, I repeat IS NOT, Freeware.

    It is, in fact Free Software. There is nothing proprietary about it. It is fully Open Source and is licensed under a Free Software License.

    As you seem unable to tell the difference between Freeware (which is Closed Source Proprietary Software made available at no monetary cost... there is almost always a hidden cost) and Free Software (which is Open Source Software licensed under a Free Software license compatible with the GNU General Public License, and can be made available at no monetary cost or for a monetary fee, at the developer/distributors discretion... read the GNU GPL) I think it is necessary to remind you on a regular basis, until you get it right.
