Preparing to use the Edge Browser component
Because TWebBrowser uses the Operating System-supplied Internet Explorer WebBrowser browser control there is no preparation required; it will work wherever Windows has the Internet Explorer control available.
On the contrary, Microsoft Edge is not an Operating System component at the time. Because of this you need to ensure that these items are installed on your computer before you can run an application that uses it:
The Microsoft Edge Chromium-based browser currently available from https://www.microsoftedgeinsider.com/download (Canary channel version whilst the WebView2 SDK is in pre-release, currently the minimum required version is 82.0.430.0).
The WebView2 control, currently available through NuGet at https://www.nuget.org/packages/Microsoft.Web.WebView2 or via GetIt package manager.
This applies to compiling and executing the application on your development machine, and also on the end user’s machine.
With both these installed, the TEdgeBrowser will function and use the Edge WebView2 browser control to render web content.
