Good Day,

We have a client that wants to run our Excel Add-in (web-based Office Add-in written with offices), 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

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, as in can we install an EdgeHTML webview runtime while not having Edge installed?
If so can someone point me into the right direction on where to get this runtime from?

    The client will have to install Edge to get the EdgeHTML webview installed.

    The line you reference for the version of office is for Microsoft 365 versions. If they are running non subscriptions version 2008 it's not even on the list (https://learn.microsoft.com/en-us/office/dev/add-ins/concepts/browsers-used-by-office-web-add-ins) and it wouldn't support Office Add-ins since it's tool old a version of Office.
