If you attempt to run php.exe on Windows you may get an error involving the following DLL.
MSVCR110.dll
The resolution to this is to install “Visual C++ Redistributable for Visual Studio 2012 Update 4”. Note that you should install the 32-bit version even if you are using a 64-bit operating system!
This can easily catch people out first time, however you can just install the 32-bit version over the top.
