Starting with version 3.5, Python requires the Universal C Runtime,
which is an OS component that was introduced in Windows 10 and
backported to previous versions, including Windows Vista (service pack
2). Python's installer should attempt to install the CRT update, but
from what I've seen this isn't reliable.

Ideally, it shouldn't be necessary to manually install the CRT update
since Windows Update includes it. Enable optional updates, and keep
your system updated. That said, if you can't or won't use Windows
Update, then you can download and install standalone updates.

The above requires Vista service pack 2 (SP2). The system properties
dialog should say whether SP1 or SP2 is installed. Your system should
be running SP2 if Windows Update is enabled. If you're not even
running SP1, you'll have to install SP1 and then SP2. The system
properties dialog will tell you whether you're running 32-bit or
64-bit Windows.
