title: PyInstaller WARNING: lib not found
body: <p>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 <code>pyinstaller --onefile --noconsole myfile.py</code>, and it outputted <em>a lot</em> of warnings:</p>

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