open your command prompt ( or terminal ) with ctrl+alt+t, then type
"sudo apt-get install wine"
and type your password. while you type your password, you won't see it but trust me, you're typing it lol.
then let him download ecc. ecc. then double-click on the gp bikes installer and it's all done. then you can do the same, the installer is the same so you won't have problems.
