nfcpy on windows 7 - [Error 193] %1 is not a valid Win32 application

Question

I want to work with nfcpy on Windows 7. Thus, I followed the instructions from https://nfcpy.readthedocs.io/en/latest/topics/get-started.html#installation

When I execute python-m nfc, I have the following error:

$ python -m nfc
Traceback (most recent call last):

WindowsError: [Error 193] %1 is not a valid Win32 application

I tried with 2 different python 2.7 installer version:

-> Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:25:58) [**MSC v.1500 64 bit (AMD64)**] on win32
-> Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:19:30) [**MSC v.1500 32 bit (Intel)**] on win32

I have the same error with both.

Copy MS32\dll\libusb-1.0.dll to C:\Windows\SysWOW64 directory.
