Windows7 64-bit, Pyside6, PyQt6, ImportError: DLL load failed while importing QtCore: The specified procedure could not be found

Question

I installed PySide6 and PyQt6 by following command:

python -m pip install PySide6

python -m pip install PyQt6

But when I try to run import PySide6.QtCore or import PyQt6.QtCore , then I get this error: ImportError: DLL load failed while importing QtCore: The specified procedure could not be found. But when I run import PySide2.QtCore or import PyQt5.QtCore , then all works fine.

I tried a lot of tips found on StackOverflow, but nothing helped me.

Answer 1

Windows 7 and 8 are no longer supported by Qt6.
