Program can't start because msvcr120.dll is missing from your computer / Programm kann nicht gestartet werden, weil msvcr120.dll auf dem Computer fehlt

Recently i got the error message whe trying to start a program:
"Program can't start because msvcr120.dll is missing from your computer / Programm kann nicht gestartet werden, weil msvcr120.dll auf dem Computer fehlt"
on my computer.

How I fixed it:
These Dll's are part of the Visual C++ Redistributable Packages für Visual Studio 2013.
The packages can be downloaded here: http://www.microsoft.com/de-de/download/details.aspx?id=40784

For a 32 bit OS, it's enough to install the vcredist_x86.exe package. For a 64 bit OS also install the vcredist_x64.exe.
