Fix Class Not Registered Error When Opening Pictures In Windows 11/10

Still having problem !

Another option is:
Settings -> Apps -> Installed Apps -> Photo Viewer[or any other photo viewing app you use] -> Advanced Options -> Repair.

That worked for me. Hope this helps anyone else who doesn't find help from the other options.

Thank you, all i had to do was repair and it fixed, (Go Settings, Apps, Installed Apps. look for you the thing you wanna fix click on it scroll down then press Repair if nothing else works you'll have to Reset it ig)

Mate, Can you help me with my problem?, My laptop suddenly turned off for no reason and i was so mad that i hit my laptop hard and when i open my laptop i just saw my laptop sound says "No audio output device is installed" And when i check in device manager i can't find my "Sound, Video and game controller" and when i search it in google whys it missing they said i didn't installed my sound card properly and i can't also see my "audio inputs and outputs" i wonder why it happened but i can still see my "Sound, Video and game controller" when i press View and Show hidden devices in Device Manager, When i check the properties it say's "code 45 "
