I'm not sure, and it's an excellent question. Anaconda stopped
installing Python on XP at 3.4.3.  python.org doesn't install 3.5 on XP,
but I don't know which build was the last one that would. 

Anaconda and python.org do have completely separate and different build
processes, but I suspect the incompatibility for XP SP2 in both has to
do with failed attempts to install Visual Studio 2015. I've seen it too
many times not to be fairly sure of that. XP SP3 evidently does work, if
Michael Torrie had no problem.
