 We recommend using the [Msys2](https://www.msys2.org/) environment to install most of the required tools. We support Windows 7 and up. Once Msys2 has been installed, launch the Msys2 terminal application, and enter the following commands
 
 ```
-pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-freetype mingw-w64-x86_64-pkg-config mingw-w64-x86_64-fltk git make python
