Entry Point Not Found : The procedure entry point CreateDXGIFactory2 could not be located in the dynamic link library dxgi.dll

[Deace]

Hello,

I created a Qt application compiled with Qt 6.6.0 and MSVC 2019 64-bit. Following the instructions, I replaced the related .dll files with the originals, including qwindows.dll. The application works fine on Windows 10, but on Windows 7, it encounters an issue:

"Entry Point Not Found: The procedure entry point CreateDXGIFactory2 could not be located in the dynamic link library dxgi.dll."

Thank you for any help or suggestions you can provide.

1. You must compile your app against Qt 6.6.2
2. Make sure to replace Qt6Gui.dll

@kleuter I am using the dll files copied from the qt6_x64_to_run_on_windows7.Is that the correct way for utilization?
