A portable dbus package could be downloaded from https://download.opensuse.org/repositories/home:/rhabacker:/branches:/ windows:/mingw:/win32/openSUSE_Leap_42.3/noarch/mingw32-dbus-1-portable-1.12. 12.77c650f41.12.10-37.1.noarch.rpm
After unpacking the rpm file with 7z on Windows and opening a command shell, running the command 'qdbus' should trigger the related code (with WINXP SP2 compatibility set)
