Movie Maker and Photo Gallery won’t install

I upgraded to Windows10, but when I did, Movie Maker would not load or play my video files that previous worked fine.  So, after days and days of reading various posts and trying to uninstall, reinstall and fix it, I reverted back to Windows7.  I have now uninstalled Live Essentials 2012, restarted, it did not show up in my list of programs or in control panel programs.  I then reinstalled Movie Maker and Photo Gallery 2011 from the Microsoft site.  It said they installed successfully and yet they are not there.  The other Live Essentials ARE there, messenger, etc.  If I try to install again, it just skips to the end and says they are all installed and "Done."  How to get my Movie Maker back?
