Camera App Not Working After Mesa 3 Update

Article #17183

Summary: If the camera app stops working after a firmware, OS Patch, or Windows update, download and run the Mesa 3 Windows Camera Rollback Tool.

To restore the camera functionality, download and run the Mesa 3 Windows Camera Rollback Tool.

This tool returns the Camera app to a working version and prevents it from updating to a newer version that could reintroduce the problem.

About this Issue

After updating the firmware, OS Patch or Windows OS, the Camera app on the Mesa 3 Windows tablet may stop working. The front and rear camera preview windows are blank and display the following error:

0xA00F429F <WindowShowFailed> (0x8007007F)

Updating the Windows OS, reinstalling the Camera app, or resetting the Windows OS to factory defaults does not resolve the issue.
