Cannot install using pip

I'm trying to install matplotlib for python 3.6.3 using, but I keep getting this exception all the time. I have tried using the whl files too, to do it manually, but same result. I'm using this link to get the whl:

https://www.lfd.uci.edu/~gohlke/pythonlibs/#setuptools

Also tried Anaconda, and python 2.7,3.4 and 3.5, and still can't fix the issue.

Exception:

Try upgrading pip

pip install --upgrade pip

You might have to use the full path to pip, if it's not in the PATH variable, like so:

C:\Users\Marcin\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pip install --upgrade pip

Edit: After searching and finding some duplicates on the web (with no solutions), it seems to me it might have something to do with the path of your python installation. Such as: duplicate 1, and duplicate 2.

Is there a reason its not installed on the default C:\Python36-32 folder? You might want to download and install the windows msi installer for python in the recommended way, and see where that gets you.

Solution:

After OP's comment, it seems that moving Python to C:\ path (preferably with a clean install with windows .msi from python.org should fix this issue.
