What have you tried already and where did you get stuck?
Just in case: If you tried to start MarieSim.jar file by double-clicking on it, and you only got to a message telling you that the app cannot be started for security reasons, try ctrl + click, then click Open and confirm that you know what you're doing. From that on a double click will work too.
