class not registered

Hi Sheila,

The error Class Not Registered may affect many applications. It can be due to changed changes on the Default apps. We'd like to ask the following to help us out on this:

• Can you elaborate the troubleshooting steps that you've done so far?
• Are you able to tell us when did this happened and how long is this ongoing?
• Were there any newly installed applications or updates applied on the device?
• Do you have another user account we can use on your device?
  

 

photo app in windows 10 wont load

my photo app wont open, and I cant uninstall it for it does not come up in the apps list in the settings. But it is in the all apps list.

When I have tried to reinstall it from playstore it says already installed. But wont open, and the new Twinui default photo view app wont open any jpeg files it say "class not registered".

I have followed other suggestions of troubleshooting, and system scan with no results.

Any suggestions?

regards
