ImportError: DLL load failed: %1 not a valid win32 application!

I run the below code in win8.1 64bit and python 2.7.3:

import sys
from PyQt5 import QtWidgets

results in:

 ImportError: DLL load failed: %1 not a valid win32 application!

Hi @chinant,

Could you try this?

:: From a cmd.exe terminal
$ pip install python-qt5
$ python

>>> # Continuing from Python
>>> import platform
>>> platform.architecture()  # Make sure your Python is 64-bit
('64bit', 'WindowsPE')
>>> from PyQt5 import QtWidgets
>>> # Did it throw an error?
