Symptom
The Procedure “Run script” with the option “Directly enter script code” does not show the script editor.
The Start page is not shown and leads to a crash of a component.
Companion is not loading.
The Comment View is not loading.
Cause
On some older OS (Windows Server 2016/2019) the Edge browser is not installed, but Visum uses some components of it.
Resolution
Install MS Edge manually
Visit https://developer.microsoft.com/en-us/microsoft-edge/webview2 and download the “Evergreen Bootstrapper”, leading to a file “MicrosoftEdgeWebview2Setup.exe”.
Install this as Admin. (If the setup reports that "Microsoft Edge Webview2 Runtime" is already installed, Edge was already present.)
- Restart Visum.
