Sims 3 Island Paradise is not displayed in the launcher and game, though installed ?!
 

Hello!
I've been wanting Sims 3 games for a long time, but I can not load a save as Island Paradise is not on my PC. Origin, however, states that it is installed. I bought the game from g2a. I wanted to uninstall and reinstall it, but because of the new launcher, I do not know where to go. Or if I go to the game in Origin, there is "download" but if I click on it nothing happens. I do not know what else I could do.
Thanks in advance!
