Jupyter notebook starting error - Win7 64Bit [anaconda2 4.4.0 ]

Question

I'm new to anaconda ,After fresh anaconda 4.4.0 on win 7 64bit I get the following crash:

(C:\ProgramData\Anaconda2) C:\Users\LordTitiKaka>jupyter notebook
Traceback (most recent call last):

y", line 6, in <module>
    from . import (constants, error, message, context,
ImportError: DLL load failed: %1 is not a valid Win32 application.

I've tried re-installing pyzmq also removed any previous python2.7 installation this is without any effect

How can it be fixed ?

Just install the 32-bit version of Python2.7. You may have to re-install Jupyter and reset Environment variables, currently is trying to load a **none 32-bit** version of the DLL — Enrique Bruzual, Sep 17 '17 at 01:14
@EnriqueBruzual did that(install py2.7 32bit) + remove/add of pyzmq + jupyter , no change in error . how can make the conda point to the right python — LordTitiKaka, Sep 17 '17 at 07:44

after looking on this link I understood that I need to find any remnants of python on my PC and delete it

I've remove anaconda and re-install : did not work

remove all Python installation and re-install : did not work

than I figured it may look for some local packages , so I've removed all Python related under roaming : worked
