For deployment on Windows, the Microsoft Visual C++ Redistributable is required.

I feel like this should be mentioned somewhere. Maybe DiscoverOrDownloadSuitableQtRuntime() could even do this? Or maybe the download could be self-contained to not require the system wide vs redist packaage. Or maybe it could download the MinGW build instead.

Ya, I think we should add a check to DiscoverOrDownloadSuitableQtRuntime to ensure the proper VC++ lib is installed.

Using MinGW would be ideal, because we can then ensure our Qt works on all Windows platforms, but it would require me to change our build process a bit, which I don't have the time to do at the moment.
