no action after screen with camera icon. Eventually message appeared " something went wrong: here is message code if needed: 0x400F4271>MediaCaptureFailedEvent>0xC00D3704. We seem to be moving ahead a step at a time. Next suggestion?

 

camera not working

If you have the camera connected to the computer, I would suggest that you disconnect the camera and then try to open the Camera app.



If the camera app opens, follow the steps below:

• Press “Windows key + C” from your keyboard to open “Charms bar”.
• Select “Settings” option.
• Select “Permissions” option.
• Turn on “Allow this app to access your: Webcam and Microphone” option.
• Lose the app by pressing “Alt key + F4” from your keyboard.
• Reopen the Camera app.
• Connect your camera and then check how this app works.

Goodluck!
