[SOLVED] Can't find installed apps

[cediegamotin]

Hi! I want to change default apps (MP4 = VLC) but windows 10 doesn't recognize my installed programs, I just want windows 10 to recognize my installed apps

Does it show in settings/apps/default apps
Click Choose default application by file type & scroll down to mp4

I don't have it installed but if I chose look for app on the store, vlc shows up if I search for it... so even if its a choice it won't work?
