ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden.

I downloaded the 4.3.0 version for Windows. All files have been extracted. I copied the CV2 folder from the Python folder to

C: \ Users \ Dj EKI \ AppData \ Roaming \ Blender Foundation \ Blender \ 2.82 \ scripts \ addons.

The script reports:

Traceback (most recent call last):
File "D:\Blender Proejekt\3D MoCap QRCode.blend\Text", line 1, in <module> File "C:\Users\Dj EKI\AppData\Roaming\Blender Foundation\Blender\2.82\scripts\addons\cv2__init__.py", line 96, in <module> bootstrap() File "C:\Users\Dj EKI\AppData\Roaming\Blender

Foundation\Blender\2.82\scripts\addons\cv2__init__.py", line 86, in bootstrap import cv2 ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden.

I tried the same with VS19. It has the same bug.

C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\Lib\site-packages\cv2

4.2.0 works great from pip. But i need 4.3.0, because i need qrCodeDetector().detectAndDecodeMulti().
