This is Qt 6.7.2 backport that runs on Windows 7/8. The repository contains patched source files from the qtbase module.
Approach is based on this [forum thread](https://forum.qt.io/topic/133002/qt-creator-6-0-1-and-qt-6-2-2-running-on-windows-7/60) but better: many improvements amongst important fallbacks to default Qt 6 behaviour when running on newer Windows.
- After replacing qtbase source files with the patched ones from this repository, you can compile Qt yourself using compiler and build options you need.
- You can use our [compile_win.pl](https://github.com/crystalidea/qt-build-tools/tree/master/6.6.2) build script (uses Visual C++ 2019 with OpenSSL 3.0.13 statically linked)
- You can download our [prebuild Qt dlls](https://github.com/crystalidea/qt6windows7/releases) which also have Qt Designer binary for demonstration
