We have a client that wants to run our Excel Add-in (web-based Office Add-in written with office-js), however, they don't have Edge or IE installed. They are running Version 2008 (Build 13127.21766) of Excel, which according to the documentation from Microsoft uses the EdgeHTML WebView (Edge Legacy)
I know with the WebView2 runtimes you can install the runtime separately since Windows 8.1 and 10 didn't come with that runtime. Can the same process be followed for the EdgeHTML WebView (Edge Legacy), as in can we install an EdgeHTML WebView runtime while not having Edge installed? If so can someone point me in the right direction on where to get this runtime from?
The only way to get the EdgeHTML webview installed is to install Edge.
