ArcGIS Pro requires Microsoft Edge Webview2 but it is already installed

[WoodRiverWolfProj]

Hey all,

I am trying to install ArcGIS Pro onto a fairly old computer running Windows 10. Initially, when I tried to run the installer I could get through the initial step of creating a file location for ArcGIS, then I would get the message that "ArcGIS Pro requires Microsoft Edge Webview2 Runtime x64" and could proceed no further with the installation. I checked that the webview2 application is installed on my computer and Windows is fully updated. Also tried to install Webview2 using the standalone installer and it says that Webview2 is already installed on my computer. Next I fully removed Webview2 and Microsoft Edge from my computer and downloaded both again. This time, I was able to fully install ArcGIS Pro to the point where it starts to launch, only to get the same message. Does anyone know why ArcGIS is not able to use Webview2 and how I can troubleshoot this?

something to check, although not much is referenced about webview2 in the support site

Hopefully this can help someone else: I was having the same issue, but running the webview2 installer again as an administrator got it to work. Per the documentation: "A per-machine installation (the default) of ArcGIS Pro requires a per-machine installation of WebView2 Runtime. To do this, right-click the WebView2 installer and click Run as administrator."
