I have been trying to install windows movie maker because my previous movie maker had gone corrupt, I had tried to do a complete uninstall of windows movie maker but it appears there are some possible files remaining due to every attempt of reinstalling leading to essentials telling me that Windows Movie Maker & Photo Gallery are already installed.

I've followed many different methods online but nothing appears to be working as intended, is there a special way I could completely discard of all remaining Movie Maker & Photo Gallery files so I could reinstall them properly?
