Question

When I try to install the Design & Compose Designer version 21.04, I get the following error :

!ENTRY org.eclipse.osgi 4 0 2022-01-28 07:55:24.560
!MESSAGE Application error
!STACK 1
org.eclipse.swt.SWTError: Not implemented [WebView2 runtime not found]

What is causing this and how can I solve this issue?

Answer

The 21.04 Desktop Designer now embeds Edge instead of Internet Explorer. Edge uses the WebView2 runtime and if that is missing on your system, the Designer will not be able to start.

You can download WebView2 using the following link : https://developer.microsoft.com/en-us/microsoft-edge/webview2/#download-section
