Trying to use command line but getting a .dll error.

[i73]

I'm trying to access the hou module for command line (windows) Regular Python Shell (python 2.7) The sideFX doc [www.sidefx.com] But when I append my env variable ('C:\Program Files\Side Effects Software\Houdini 16.0.671\houdini\python2.7libs') and append it also to my sys path in the python shell I get a:
 

File "C:\Program Files\Side Effects Software\Houdini 16.0.671\houdini\python2.7libs\hou.py", line 19, in <module>
    import _hou
ImportError: DLL load failed: The specified module could not be found.

In my libs folder I don't have a ‘_hou.py’ I only have ‘_hou.pyd’

After trying to figure it out myself I am unable to get this working, anyone have a suggestion for me?
