Django registration error after switching interpreter to Python 2.78 - django

Question

I initially had python 3.4 installed with django 1.65. But i searched and found out Django registration doesn't work with python 3. So I downloaded python 2.78 and even uninstalled python 3.4.
However When i am on url http://www.localhost:8000/accounts/register/ and try to register a user an error comes up. It seems like its django registration is still reading my old virtual env linked to python 3.4 and its path. I have edited my environmental variable PATH to delete any Python 3.4 and replaced with Python 2.7. But still same error occurs. I'm new to web development. Sorry if I didn't provide enough detail or to little detail.
