Trouble installing Python 3.5.0

[Nagy László Zsolt]

>> Hello,

>> I installed 3.5, "successfully" as the installer indicated, yet the program wouldn't run, with the following error message: "...failed to start because api-ms-win-crt-runtime-I1-1-0.dll was not found. Re-installing the application may fix this problem." I reinstalled, but no luck.

You will find this under "Unsupported Operating Systems" section.
Although Vista is not mentioned there, but Python 3.5 is built with
Microsoft Visual Studio 2015, and its runtime library is AFAIK does not
work under Vista.
