Which version of Inteenimator (Sims 2) should I download and how do I do it?

I have Sims 2 Double Deluxe (Base game, Celebrations Stuff, and Nightlife), Bon Voyage, Glamour Life Stuff, University, and Fun With Pets (Pets, Family Fun Stuff, and Mansion and Garden Stuff). Which version of Inteenimator should I download? I know you have to download Winzip or Winrar as well so could someone provide a link for that and tell me what to do with it? Thanks! ;)
