Problem with installing Sims Island paradise.

Hello everybody,

When i try to install the game, (by opening the setup). I get, as normal, the notification that it needs to update the sims 3 first. If i click okay, it immediatly tells me there is an error and i cannot go any further.
So, when i was searching for a solution on the forum, i read that i'd have to select the support update setup. However, this gives me an error right away,

help! How can i get this game working?
What am i doing wrong?
