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

Problem

When you start SmartFTP 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.

Solution

1. Install Windows Updates:
   Go to Start - Control Panel - Windows Update
   Check for updates
   Install all available updates.
   After the updates are installed, restart your computer.
   After the restart repeat the steps above again until no more updates are available.
    
2. Download the Visual C++ Redistributable:

   For Windows 64-bit
   Visual C++ Redistributable for Visual Studio 2015 (64-bit)
   For Windows 32-bit
   Visual C++ Redistributable for Visual Studio 2015 (32-bit)

3. Run the vc_redist.x64.exe (64-bit) or vc_redist.x86.exe (32-bit) and select Uninstall
4. Run the .exe again and select Install
