# Installing support Applications

To get a fully functional McStas installation, a few support applications are required. Essentially, you will need a C compiler, Perl and Perl-Tk, as well as a plotter such as Matlab, Scilab or PGPLOT. These should better be installed before McStas.

Under Windows, we recommand to avoid using spaces when specifying the location of packages during their installation.
