Throw error when WebView is missing

[Madis0]

Ideally on any platform

system webview is:

• in macOS, an integral part of the system and is not removable
• in Linux, bundled inside the AppImage
• in Windows, uninstallable but is installed by default
  so, only windows requires treatment when webview is missing. relevant microsoft documentation: https://learn.microsoft.com/en-us/microsoft-edge/webview2/concepts/distribution

I'm thinking installing WebView2 Runtime after asking the user if it is not present

By "installing" you mean running the official installer as headless? I'm thinking that we could just give the user the installer link, so that we don't have to deal with

• system files
• admin permissions
• probable restart after installation

[vgskye]

WebView2 Runtime installers are designed to run headlessly for this exact purpose so it should be fine?

I thought that if we use the headless part, we still have to get the admin perm and handle restart ourselves. But I guess you're right, we can test and see.
