[Problem/Bug]: Windows 10 64Bit Silent Evergreen Standalone install fails with 0x800405fe

[EricAustinYu]

What happened?

We are installing WebView2 from the Evergreen Standalone installer with the /silent option. The machine may have already had a newer version installed. From the logs it looks like an issue downloading some files (I thought standalone was offline).

Usually more info would be in the parentheses after the error code, but for some reason this one is blank. We're curious what this error code means.

Installation succeeded on a subsequent attempt:

@EricAustinYu could you share the whole log? If you don't want everyone to see the file, you could share it with me via email at lzhao@microsoft.com.

I have sent the full log to that email. Thanks!

Confirming that I have received the full log file and forwarded to the Edge deployment team. Initial assessment is that there might be not much info in the log to figure what this 0x800405fe means. The reason there is no message is because it is not a known error to Windows. I'll continue to ping them and update this thread when we have things to share.

FWIW, it is recommended to check whether there is a higher version of WebView2 runtime already installed before trying to install it. Like in this case, there is no need to install the old 110 version when 119 is already installed. https://learn.microsoft.com/en-us/microsoft-edge/webview2/concepts/distribution#detect-if-a-suitable-webview2-runtime-is-already-installed has information on how to get installed version.
