Or maybe, if the Windows executable is created by Microsoft Visual C, use the /delayload:dllname linker option, and advise users on Windows 7 and 8, to not try to use DirectX12 (by setting the environment variable QSG_RHI_BACKEND if necessary). See https://learn.microsoft.com/en-us/cpp/build/reference/linker-support-for-delay-loaded-dlls?view=msvc-170

See https://support.microsoft.com/en-us/topic/how-to-install-the-latest-version-of-directx-d1f5ffa5-dae2-246c-91b1-ee1e973ed8c2 The dependence on DirectX12 comes from Qt 6; see https://doc.qt.io/qt-6/qtquick-visualcanvas-scenegraph-renderer.html#rendering-via-the-qt-rendering-hardware-interface. This page also says that you may set the environment variable QSG_RHI_BACKEND to one of the values vulkan, metal, opengl, d3d11, d3d12. Since d3d11.dll is also a dependency of QtGui.dll, you might try whether setting QSG_RHI_BACKEND to d3d11 works, although, since d3d12.dll is a direct dependency of QtGui.dll, I suspect it won’t; if not, you could try renaming a copy of d3d11.dll to d3d12.dll and add it to the LyX/bin directory. It sounds, therefore, as if one could compile LyX 2.4.2 with Qt 5, and that would avoid this problem. Yes? Riki
