On Windows 10 64 bit I’m currently using
Webview2 is installed in C:\Program Files (x86)\Microsoft\EdgeWebView\Application
But I think this is actually the 64 bit version thought, or at least that’s how it shows in the Task manager when running. So perhaps ensuring @Scott.E ensuring he has the 64bit versions on Windows is worth checking. To do so this post may help New Update - #4 by Patch
I’m actually running older versions of both Manager and Webview2 so would not expect to see issues with recent updates (I manually update these programs at a time convenient for me, by blocking Webviewupdate, Webview2 and Edge internet access).
