I'm going to advance a bit with this answer xq really is not entirely clear your question, but I think this may be your problem.
Starting from saying you already have Python added to the path.
Responding to Do you have to configure something in the path to work with Django?
The path to the folder that contains the Python executable
The path to the Scripts folder that must be at the same level as the python executable.
Django's folder does not.
After this you can install Django via Pip or directly by running setup.py
Ex 1 - without PIP: python <path_to_django_folder>\setup.py install
Ex 2 - with PIP: pip install django
or pip install <path_to_django_folder>\django.tar.gz
Then you can use create a project in the following way:
python django-admin.py startproject <path_for_project>
or
django-admin startproject <path_for_project>
I hope it solves you.
PS: you should study how you use virtual environments so you can use the necessary packages for each project.
