Sims 3 won't install, tries to install High-End Loft Stuff

Hello, I need some help installing Sims 3. So when I go to download Sims 3 it just simply won't install, I push download and then it says that the packs won't install so I do it without the packs and it says that a pack won't install even though I didn't push the option for packs, so I cancel the packs that I did not don't load and once I've canceled them all Sims 3 doesn't even pop up for a download option. (The High-End Stuff Lot shows up each time!)
