Problem Installing The Sims 3 World Adventure (regedit thing) [SOLVED]

I used to have The Sims 3 games, started games4theworld version since the Ambition expansion pack, but after installing all the Generations expack, my saved file couldn't load properly, so I decided to reinstall the whole thing, downloading the base game from games4theworld.

Now that I've downloaded them, I have succeeded installing The Sims 3 (base), but I cannot install The Sims 3 World Adventure. The problem is, when I'm trying to do the first step, which is to change something in regedit, I cannot find the "Sims" folder under the HKEY_LOCAL_MACHINE/SOFTWARE.

WHY? /desperate

edit: Okay, found it under Wow6432Node
