But I can get it running from pycharm (slick but with issues). When I take the kernel's IP and Port from pycharm and paste it into my browser I can get it running from there. 

I cannot use anaconda because of Arcpy, and I have dug around the jupyter files for some hints.

I'm assuming I need to add something to my path?

Answer: 
This is an old question, but try using 
`python -m notebook`
This was the only way I was able to get jupyter to start after installing it on the windows 10 command line using pip. I didn't try touching the path.
For future reference: the first hurdle of starting with Python is to install it. I downloaded the Anaconda 4.4 for Windows, Python 3.6 64-bit installer. 

After sorting the first hurdle of updating the "path" Environmental Variable, and running (at the Python prompt) "import pip", all the instructions I found to install the IPython Notebook generated errors. Submitting the commands "ipython notebook" or "jupyther notebook" from the Windows Command Prompt or the Python prompt generated error messages. 

Then I found that the Anaconda installation consists of a host of applications, on of them being the "Jupyter Notebook" application accessible from the Start menu. This application launch (first a shell, then) a browser page.

The application points to a shortcut in , a directory set during the Anaconda installation. The shortcut itself refers to a few locations.

Ready for next hurdle.
