I'm Following the instruction by evilrat,
https://forum.dlang.org/post/xljvxkqimdvvbvujczqy@forum.dlang.org

but apparently I'm to stupid to run the example.

The application quits with Error load: QtE5Widgets64.dll which is located next to the EXE-file (also Qt5Core.dll, Qt5Gui.dll and Qt5Widgets.dll).

The error is traced back to Runtime.loadLibrary() in GetHlib() in qte5.d but that's it.

Not sure what Windows does at loading the Qt5Core.dll (it looks for multiple paths where the DLL is also present but it also locks the Qt5Core.dll in the application directory - according Process Monitor) but it seems that's the last DLL which is loaded before the thread is exited.

Any hints are appreciated.

Maybe you're trying to load a 32-bit library into a 64-bit process.

Hmm, it's precompiled and the 64bit version should be a wrapper but I guess that it just doesn't work yet or needs a 64bit runtime as well. No idea where to get the runtime alone without downloading the whole QT framework...

Indeed, the 32bit build works.
