Someone graciously passed along a link to a site hosting the older patches for Sims 3 as well newer patches for Sims 3 World Adventures.
If you don't want your game to automatically update via the launcher, you can open the launcher and go to Updates. Uncheck the box to disable the automatic updates.
Then make a shortcut to the game exe from the Sims 3 or Sims 3 World Adventures directory:
XP users:
Sims 3 path:
C:\Program Files\Electronic Arts\The Sims 3\Game\BinSims 3 World Adventures path:
C:\Program Files\Electronic Arts\The Sims 3 World Adventures\Game\BinI personally use TS3booter from Pescado's site that literally boot the game. I made a desktop shortcut with that installed just like I would with the game exe.
NOTE:
Vista and Windows 7 players may post the directory paths for others to locate if they have either Vista or Windows 7. I don't use either Vista or Windows 7.
Onward to Patches:
Okay, the patches are available at
SimPrograms. You will have to choose either Sims 3 or World Adventures as your latest install.
I hope you will find this useful information to get Sims 3 the way you want to play.
