Problem: ArcMap 10.3 crashes to desktop anytime I use a Python related function (Toolboxes, Field Calulator, Etc)
How I got to this point: I was trying to gain some familiarity with Python programming and opted to use the guide of Learn Python The Hard Way.
This involved downloading, installing Python and setting your environment using Powershell.
I believe this caused some issues since there was already an installation of Python in effect from having ArcGIS Installed. There was already a "Python27" folder on my main HDD.
Question: How do I tell my ArcMap to look in the "Python27\ArcGIS10.3" folder for Python? I'd prefer to avoid re-installing ArcGIS entirely.
Screenshots for thought:
^ From initial research, I found that I should have some sort of Python directory entered into these fields, but I'm not sure what specifically needs to go in there.
