# Building OVITO on Windows

The required steps are quite involved, in particular those for building/installing the prerequisites, and the available instructions may be insufficient. Please get in touch with the developers if you want to build OVITO on the Windows platform.

You are going to need at least the following prerequisites:

- Microsoft Visual Studio 2017 or newer (64-bit command line tools for C++ development)

- Qt 5.12.x (install the msvc2017 64-bit component)

- CMake (v3.3 or newer)

- git

- zlib (v1.2.11)

- Boost (header-only component)

- OpenSSL (v1.1.0*, requires Perl and zlib)

- libSSH (0.9.0, requires OpenSSL and zlib)

- HDF5 (optional, requires zlib)

- NetCDF (optional, requires HDF5 and zlib)

- ffmpeg (v4.2.1, optional, requires MSYS2)
