Change the language

So, I instaled the new version, but now, when I open it, it's in a language I don't know.
Can someone tell how to change it to english??? or where to dowload an english version (I downloaded from here https://dolphin-emu.org/download/)
or a spanish version, or a french version, or an italian version, or a portuguese version... well you get the idea.

I can't understand anything, so I can't find the option to change the language.
