Already checked and reinstalled Microsoft Visual C++ Redistributable, the issue is still occurring.

• occ 7.4.1
• Python 3.9.12
• Win 10

Thank you in advance!

I soleved this problem by adding this line before import:

os.add_dll_directory('D:/install/OCCT/win64/vc14/bin') # replace with your occ bin directory
