Microsoft Edge and WebView2 error 0xc000007b What happened: On Nov 5, a change to how NinjaOne detects Microsoft's WebView2 component caused the 32-bit version of WebView2 to install on 64-bit Windows devices, replacing the 64-bit version. In addition to files shared by Edge and WebView2, other apps relying on WebView2 (Outlook, Teams, and others) may fail to open, displaying the error '0xc000007b'. Status: The problem has been repaired. On Nov 9, we updated our patch catalog so that the 32-bit package will not be installed on 64-bit systems. Devices that were affected may still need repair. What to do if devices are still affected: - Patch policies that auto-approve Edge and WebView2 (x64): these devices should recover at their next patch window, after the latest Edge update installs (version 157.0.4341.46 or higher). - Manual approvals: approve Microsoft Edge (x64) and WebView2 (x64) version 157.0.4341.46, then run a patch scan and apply. - Immediate manual repair: sign the user out (or reboot without signing in). From NinjaOne, run Microsoft's WebView2 Runtime x64 installer as System with /silent /install. Then sign back in and run a patch scan and apply with Edge approved. If a device is still affected after these steps, open a support ticket and include the device details. We can also provide an automation to repair devices at scale.
