New submission from Hugh C. Lauer:
Hello,
I am a university professor who regularly teaches classes in Python
programming, particular to students who are NOT computer science majors.
In preparing my course materials for next fall, I have been struggling with
setting up a Python 3.5.1
Hugh C. Lauer added the comment:
Upon further investigation, I find lots of encodings in the folder C:\Program
Files\Python35\Lib\encodings\ and lots of compiled encodings in the subfolder
__pycache__ .
Somehow, these are not being found by Python itself, or there is something

Thanks very much, Stefan. Running as administrator did the trick for Windows 10
installations. I now have a reliable, repeatable protocol that I can give to
students with little computing experience that will enable them to install

Thanks Zachary for this. On Windows 10, no PYTHON or PYTHONHOME environment
variable is set. On Windows 7, they are set. Moreover, even though I am
installing Python 3.5.1, the refer to C:\Program files\Python34 !
I will continue to
Hugh C. Lauer added the comment:
All, it seems that installation of Python 3.5.1 on Windows 7 must also be done
as administrator. Once I did that, the installation of Python 3.5.1, numpy
1.11.0, and matplotlib 1.5.1 all went seamlessly.
The only environment variable that was changed was to
