7.  Step-by-Step Installation Guides

You can find below some useful pages collecting instructions on how to install Geant4 in a detailed step-by-step tutorial:

7.1.  Building on MS Visual C++

Geant4 now builds on Windows using CMake to configure MS Visual Studio solutions which compile Geant4 using the Visual Studio C++ compiler. Cygwin is no longer required.

If your use case mandates Cygwin, you can also use CMake inside Cygwin just as you would on a Unix platform and the Visual Studio C++ compiler can be used. However, this is not supported or tested at present. If your use case mandates the use of Cygwin, then the GNUMake system can still be used, and Geant4 can still be compiled with the C++ compiler of MS Visual Studio C++ and Section 6 should be consulted to determine the needed Makefile and environment variables.

Listed below are some useful pages with instructions on how to start with the installation of CygWin, and also tips for creating a project under Visual Studio:
