python - PyInstaller WARNING: lib not found

Question

I know this type of question has been asked here before, but I did not find a working solution to it. I have a python file which I want to convert to an exe on Windows 10. I ran pyinstaller --onefile --noconsole myfile.py, and it outputted a lot of warnings:

As you can see the exe is created successfully, but it doesn't work as it should when running it.

EDIT: I ran it with debug enabled and apparently it can't import ctypes, it throws a name error. It only does this when running with pyinstaller, when running as a .py file it works fine.

Answer 1

I found the DLL's in system32/downlevel and syswow64/downlevel and copied all of them to the respective parent folders (system32 and syswow64). Something that Ritesh Singh's command will do. Try a restart after copying if it still does not work.

EDIT: As mentioned in comments, using set PATH=%PATH%;C:WindowsSystem32downlevel; before using pyinstaller or adding the downlevel folders to path in env variables might be a better idea.(not tested)
