Problem

When you start Flux Center, you get the following error message:

The program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer.

The problem is that the KB2999226 (Universal CRT) which is part of the Visual C++ Redistributable for Visual Studio 2015 failed to install.
