I had Movie Maker working on Windows 8.1. When I upgraded to Windows 10 Movie Maker stopped accepting mp4 video files from my camera. I tried to uninstall and reinstall Movie Maker but to no avail. I then decided to revert to Windows 8.1 to get Movie Maker to work. Movie Maker did not show as installed in Window 8.1. I tried to install the complete Windows Essentials 2012 package without success. I then reinstalled Windows 10, and updated the graphics, sound and motherboard drivers.
If I try to install Windows Essentials 2012 now it tells me all its programs are installed. None of these programs are available anywhere. Furthermore, Windows Essentials does not show up in Programs and Features so I can't uninstall it. How can I resolve this issue bearing in mind that all I need is Movie Maker to work?
