Tutorial First Step


Start off by installing the standalone Tcl/Tk version of ProB. Follow the instructions in Installation.

Starting ProB

Start ProB by double-clicking on ProBWin (for Windows users), or by launching StartProB.sh from a Terminal (for Linux and Mac users).


Mac users may also be able to launch ProB by double-clicking on StartProB.sh.

This should bring up a window as follows (on a Mac):

Normally, it should look as follows (on Windows):
