I’m not sure what you mean by this, our WebKit based HTMLViewer is supported on Windows 7. Whatever issues it may have should be reported, but I suspect most of what you are seeing has already been addressed (only because it sounds old and familiar). WebView2 introduces their own runtime so unless users have Edge installed you’d have to provide a way to download it with your installer (all trade-offs of course, and this does not imply we’ll never add support for WebView2, just pointing out the obvious headaches of doing so).
