# Installation on Microsoft Windows

For Microsoft Windows, Cain is distributed as an executable. Download and run the installer. The example data files are in the `examples` folder in the application directory. They are also distributed separately in the zip file `CainExamplesWindows-x.y.zip`. The mass-action solvers are pre-compiled. In order to use custom propensities you will need a compiler; Cain uses Microsoft Visual Studio 2010. If you do not already have MSVS 2010, get the free Microsoft Visual C++ 2010 Express Edition. Select the Visual C++ 2010 Express download.

To uninstall Cain, select `Cain→Uninstall Cain` from the start menu.
