Python 3.5.0 does not start.

On Windows, the following error occurs:

Python.exe - System Error

The program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer. Try reinstalling the program to fix this problem.

Tell me what to do with this.

Translation of the response from Stackoverflow (not directly related to Python 3.5, but related to api-ms-win-crt-runtime-l1-1-0.dll ).

api-ms-win-crt-runtime-l1-1-0.dll is missing when open office file

The program does not start due to the absence of the api-ms-win-crt-runtime-l1-1-0.dll library on the computer. The problem is that KB2999226 (Universal CRT) is not installed, which is part of Visual C ++ Redistributable for Visual Studio 2015.

The first solution is to install all available updates (comment: which is not acceptable for everyone, for example, because of pirated Windows or any suggestions to upgrade to Win10): Start - Control Panel - Update Windows, check for updates, install all available updates. After installing the updates restart the computer. Repeat until no updates are installed.

You can download Visual C ++ Redistributable separately:

For Windows 64-bit: http://download.microsoft.com/download/9/3/F/93FCF1E7-E6A4-478B-96E7-D4B285925B00/vc_redist.x64.exe

For Windows 32-bit: http://download.microsoft.com/download/9/3/F/93FCF1E7-E6A4-478B-96E7-D4B285925B00/vc_redist.x86.exe

Run vcredist_x64.exe (64-bit) or vcredist_x86.exe (32-bit) select the uninstall first, then reinstall it.

    I translate (if necessary) in the text of the error it is written:

    Программа не может запуститься потому-что api-ms-win-crt-runtime-l1-1-0.dll (windows library) is отсутствует на вашем компьютере. Попробуйте переустановить программу чтобы исправить эту проблему отсутствует на вашем компьютере. Попробуйте переустановить программу чтобы исправить эту проблему
