How do I install all the necessary mods? I'm a newbie.

Hello, I recently found out that there are adult mods for sims 3 and I wanted to try them, but at the beginning I had problems using this guide "https://www.loverslab.com/topic/36994-the-sims-3-complete-adult-guide/", I installed KW in the packages folder in my documents, but there is nothing in the game, even in the launcher there is nothing that the mod is enabled or working, what should I do?
