[Problem/Bug]: Installer failed to upload the Webview

[raffaeler]

What happened?

Visual Studio 2022 started requesting to update the Webview2 in the yellow ribbon.
I hit the link on the yellow ribbon, downloaded the WebView2 installer and tried to install it, but it failed with the following error:

This happens for both the Evergreen Bootstrapper and the Evergreen Standalone Installer.
If I open add/remove programs and search for WebView I cannot find any component to uninstall. Therefore even re-installation is not possible.

I initially submitted the problem in the Visual Studio 2022 website, but they told me to log the bug here.
https://developercommunity.visualstudio.com/t/Cannot-update-the-webview/10850380

The WebView2Utilities app tells me that I only have the version 133.0.3065.69 installed. The currently available installer has the same version, therefore the bug is apparently in detecting the installed version.

FYI, when I install the WebView installer on a machine without Visual Studio, it does not clearly tell whether the WebView2 runtime finished installing the WebView sucessfully or not. The installer just closes without feedback and this is not a good thing.

Importance
