You must delete all 'ATrois old mods' already installed, and then insert the "ATrois folder" in the MODs folder.
Copy the ATrois folder that is inside the RAR. This will look like this: "C:\Users\'yourname'\Documents\Electronic Arts\The Sims 4\Mods\ATrois"
Don't forget to extract the mod from inside the RAR, some people were putting the RAR file in the MODs folder without extracting.
Check if you upgraded Origin, TS4 or WW ... Usually after an update, you need to go to the game options and to reactivate the 'mods option' to work and then restart the game.
