Failed to load the Frida native extension: DLL load failed: Das angegebene Modul wurde nicht gefunden.

frida/init.py のインポートパスと _frida.cp35-win_amd64.pyd 拡張から始め、Windows 10 64 ビット上の Python 3.5 で example.py を使用して失敗を再現します。ネイティブ拡張を読み込めない理由を確認します; ドキュメント化された例で DLL エラーなしに frida のインポートが成功すれば完了です。

I used pip to install frida with Python on Windows 10 64 bit.
But if I try to do python example.py as mentioned in the docs, I get

***
Failed to load the Frida native extension: DLL load failed: Das angegebene Modul wurde nicht gefunden.
Please ensure that the extension was compiled for Python 3.x.

Traceback (most recent call last):

  File "C:\Program Files\Python35\lib\site-packages\frida\__init__.py", line 6, in <module>
    import _frida
ImportError: DLL load failed: Das angegebene Modul wurde nicht gefunden.

If I rename c:\Program Files\Python35\Lib\site-packages\_frida.cp35-win_amd64.pyd to something else, I get

***

What could be the problem and how to resolve it?
