For those of you who are waiting for @shorty943p to answer:
I found it at:
C: > Program Files (x86) > Origin Games > The Sims 4 > Game > Bin_LE
I am assuming the "The Sims 4" bit there can be any of the other titles, haven't tried Sims 3 or SimCity 4 yet but anyway ...
TS4.exe (named just "TS4" with a green plumbob icon) can be double clicked on there to start the game, or you can create the desktop shortcut first so it's there again another time, and click on the desktop shortcut. To make a desktop shortcut, click on it once to highlight it, then right click to see the drop-down menu, then hover over 'Send to', wait for that drop-down menu, then click on 'Desktop (create shortcut).
