You're running Windows 7?  That's where this usually happens.

Here's (some of) the deal: when you build a program with Microsoft
compilers (MSVC) it links in a way so that it requires certain runtime 
components. This is absolutely no different than other compilers + 
operating systems, to start with.  In this case, the msvc version 
current Pythons are built with require a component that isn't available 
by default on Windows 7, or in fact, the WIndows 8 variants, which are 
quite old (*); it is included in Windows 10.  The Python installer 
includes this piece, because it's a known issue, and it will try to 
installe it, but if you don't select an install with administrator 
privilege - and the Python devs worked hard to make it not necessary to 
do an admin install otherwise - installing it will fail... often 
silently from the point of view of what you as the user see  (probably 
will be in the logfile). Sometimes it fails even with admin privilege 
AFAIK. Easiest workaround is to install the package that contains it - 
manually copying in dll files rarely works as expected.  It comes from 
"Visual C++ 2015 Redistributable", if I'm not remembering wrong - that's 
something you should be able to find and install.


(*) Win7 came out in 2009; Win8 in 2012; Win8.1 in 2013. It's somehow 
not entirely unsurprising that they wouldn't come with a piece of 
software that was introduced with Visual Studio 2015.
