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

Question

I am facing this .dll library missing error:

This programme can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing. Try to reinstall this.

When I try to open an Microsoft Office file.

How do I solve that?

Answer 1

The default solution is to install KB2999226 of Microsoft.

Answer 2

This error is usually caused by the missing Visual C++ Redistributable file, which is a required dependency for most of the application on Windows Computer.

Download Visual C++ Redistributable from here and install it. After installing this, Reboot the system.

Answer 3

While the answer from alireza is correct, it has one gotcha:

You can't install Microsoft Visual C++ 2015 redist (runtime) unless you have Windows Update KB2999226 installed (at least on Windows 7 64-bit SP1).

Answer 4

In case nothing of the previous answers worked, add one of these paths to your PATH environment variable:

C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x64
C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x86

Of course, make sure they exist first and that they contain the DLL files needed. If they don't exist, try installing "Windows Universal CRT SDK" from the Visual Studio 2015 or Visual Studio 2017 installer.
