I have Power Tracks 2014 installed on 2 computers: One with windows 7 and the other with windows 10, latest updates.

On the windows 7 machine Power Tracks will let me import an MP4 to extract the audio (typically after making a tutorial I extract the audio to clean it up, then put it back in the video)

But the windows 10 machine won't open it. I installed the K-Lite codec pack but it still won't open it. Anybody know what I need to install in order for Power tracks to work the same on both machines?
