Python has stopped working

Blender 2.78 and blend4web latest both downloaded / upgraded today in user preferences …
Windows 10 64 bit and Python 2.7 installed.
Any hints please ?

178280 unhandled win32 exception in python.exe

Python 2.7.1 (r271:86832, May 5 2016, 05:42:33) [MSC v.1600 64 bit (AMD64)] on win32

Actually Blender 2.78 uses Python 3.5 and official Blender distribution contains it.

Blender doesn't run at all? Or it stopped working after Blend4Web installation?

Blender work as far as I see… I was able to load a blend file downloaded from somewhere… a fireworks example.
I was also able to render it. But I was planning to look more deeply into the balloons example, I know you have it in the http://localhost:6687 somewhere, that's why I did clicked after loading this local page on "project manager" link which contains examples but then Python has stopped working window appear. I do have also installed Python 2.7 as I did mentioned.

I will proceed to uninstall it and install eventually the 3.5 or nothing… and see if it will be the same

If you have other hints please let me know

No changes either with 2.7 uninstalled and or 3.6 installed … same

But http://localhost:6687/apps_dev/code_snippets/code_snippets.html?scene=camera_animation works fine and all other
at http://localhost:6687/apps_dev/code_snippets/code_snippets.html?scene=canvas_texture

Only problem with python occurs when http://localhost:6687/project/ is accessed

Could you type
in Blender Console? The result should be the path to the python binary, which Blender uses. Try to run this python binary in Windows cmd.

I get 'C:\\Program Files\\Blender Foundation\\Blender\\2.78\\python\\bin\\python.EXE'

what should be done ?
