[Python-Dev] [Webmaster] Python keeps installing as 32 bit

I can say for certain that Python 3.5.1 will install as 64-bit as that's
what I'm personally running on the Windows 10 laptop that I'm writing this
email on.

If you look at https://www.python.org/downloads/release/python-351/ you
will notice there are explicit 64-bit installers that you can use. Did you
get your copy of Python by going straight to python.org/download and
clicking the yellow "Download Python 3.5.1" button?
