There you go. py.exe probably used Python 2.7 rather than Python 3.6. What Python version starts if you just run "py"? If it *is* Python 2.7 that's the default, you can use "py -3 -m pip" etc. Or, frankly, if you don't use Python 2.7, you might as well just uninstall it to save you the headaches. -- Thomas -- https://mail.python.org/mailman/listinfo/python-list
