Webview2 exe missing after edge update

After the recent edge update, the webview2 exe is not updated together.

C:\Program Files (x86)\Microsoft\Edge\Application\151.0.4129.59\msedgewebview2.exe is missing.

This breaks webview2 apps on Windows.

Is there some change to location of webview2? Any new API to get the location of the new webview2, or this is a genuine bug that need to be resolved by Microsoft?

  • The path you checked belongs to the Edge browser, not the Evergreen WebView2 Runtime. WebView2 is serviced separately and normally uses C:\Program Files (x86)\Microsoft\EdgeWebView\Application<version>\msedgewebview2.exe, even when Edge and WebView2 binaries are hard-linked on matching versions. An application should not hard-code the Edge\Application path. First verify the Evergreen Runtime is installed under Apps > Installed apps, then run the official Evergreen Standalone Installer with administrative rights to repair or reinstall it. Restart the affected apps and Windows afterward. Developers should detect the installed runtime through WebView2’s environment/version APIs and let CoreWebView2Environment choose it; browserExecutableFolder is for an intentionally packaged Fixed Version runtime, not for locating Evergreen files. Also confirm security software has not quarantined the executable and that the EdgeWebView folders retain their default read-and-execute permissions. If the correct runtime folder exists but apps still fail, collect the app’s WebView2 initialization error and runtime version before escalating.
