python pip - V points to old version of python

[metalray]

Dear Python Experts,

When I run pip -V in my virtual environment I read:

(env_python36) C:\Users\myuser\Downloads\iwt_django36\iwt_django\iwt_django\env
_python36>pip -V
pip 7.1.2 from c:\program files\python35\lib\site-packages (python 3.5)

I use Windows 10 and have installed Python 3.6 in
C:\Users\myuser\AppData\Local\Programs\Python\Python36\python.exe

How can I point to the new version of Python?
