The Sims 3 Expansion Pack Installation Order
Expansion/Stuff Pack Install Order and Manual Uninstall of EPs/SPs
This page covers the install and uninstall process for The Sims 3. We'll show you the proper install order and what to do if you cannot get a Sims expansion or stuff pack cleanly removed from your system. The information on this page comes from our technical help board on the forum. My goal here is to combine information, giving you a helpful guide to visit when you need to reinstall your games.
The Sims 3 Installation Instructions
This section lists the proper install order for The Sims 3, Expansion Packs and Stuff Packs. Installing each piece of this massive game in the proper order is recommended for a stable experience.
According to Electronic Arts, you no longer need to install The Sims 3 Expansions in a specific order. I would still recommend following the list below just to ensure everything works properly. While we are told it is no longer necessary, we have a game that has a lot of bugs and I personally will not deviate from this order. All need to be put in anyway, so why not install in the order they were released?
During the install process, you will be prompted to patch up between Expansion Packs, which is necessary. Go through the motions, and after the hefty install process is over you can again play The Sims 3!
Install your games in this order, and everything should be fine:
First you'll of course install The Sims 3 Base Game, then install:
The Sims 3 World Adventures Expansion Pack
The Sims 3 Ambitions Expansion Pack
The Sims 3 Late Night Expansion Pack
The Sims 3 Generations Expansion Pack
The Sims 3 Pets Expansion Pack
The Sims 3 Showtime Expansion Pack
The Sims 3 Supernatural Expansion Pack
The Sims 3 Seasons Expansion Pack
The Sims 3 University Life Expansion Pack
The Sims 3 Island Paradise Expansion Pack
The Sims 3 Into the Future Expansion Pack
Installing Stuff Packs
Installing Stuff Packs in any particular order has never been a big issue as they don't make huge modifications to the game as Expansion Packs do.
Installing and Uninstalling Worlds:
Worlds such as those found on the Sims 3 Exchange, and Barnacle Bay, can be installed at any time. They don't modify the gameplay, so they are also easily removed.
Uninstalling The Sims 3 Manually
Normally you can uninstall The Sims 3 and any of the expansion and stuff packs through Control Panel using the program to add/remove programs. However, if the uninstall does not go well, you can uninstall each of the games manually. Below are links to the EA Customer Support site that give specific instructions on how to manually uninstall the games.
Uninstall Sims 3: World Adventures
Uninstall Sims 3: Ambitions
Uninstall The Sims 3: Late Night
Uninstall Sims 3: Generations
Uninstall Sims 3: Pets
Uninstall Sims 3: Showtime
Uninstall Sims 3: Supernatural
Uninstall Sims 3: Seasons
Uninstall Sims 3: University Life
Uninstall Sims 3: Island Paradise
Uninstall Sims 3: Into the Future - not yet availalble
You can search EA's support Site from any of the links above if you for some reason need to manually uninstall any of The Sims 3 Stuff Packs - many support articles on other topics are also found there. If I found myself in a situation where I had to follow all these processes, I would probably just reinstall my computer's Operating System rather than go through all the steps you'll find in each of these. It would be much faster. Hopefully, you only need one instruction set.
Though that is an option, just installing the expansions as you get them shouldn't be that impacting on your game.
And in case I misunderstood your question: You can have any/all of the expansions installed at the same time.
Now my game is forever ruined.... I have no idea what to do.
