Issue setting up python local environment - Python 2.7, Python 3.4, Canopy

I am having a problem setting up my local python environment for the tutorials on Treehouse. Before starting Treehouse, I had python 2.7 installed on my Windows 7 computer and was doing most of my work from a previous online course in Enthought Canopy.

(I'm Not sure if its relevant, but I was never able to actually run the interpreter from the windows command prompt, I always had to run Idle or canopy.)

As the instructions stated, I downloaded and installed python 3.4 and was then able to run python from the windows command prompt like the video showed.

This is when I encountered my first problem: 1) I typed python in the command line, and python 2.7 began running. I also tried entering "python 3" and "python3"; the only thing it did was result in an error.

My second problem: 2) Inside the command prompt, I tried using python 2.7 to install and run virtualenv. I got an error that it is already installed and located within Canopy. See error below

Next, I tried opening up the python shell for version 3.4 and entered pip install virtualenv. A syntax error was returned highlighting the word install.

Ideally, I would like to be able to run python 2.7, python 3, and Canopy. After searching online I can't seem to find anyone else with this issue.

I apologize for the long post
