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
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.

I bought Sims 3 and Sims 3 Pets yesterday.
I also have Generations and Seasons.

I tried installing Sims 3 and Pets, and pets wouldn't work..
Do I actually have to have every expansion pack to play the game every if I don't want them all??

my latest game is the sims 3 university life, but i am installing older expansion packs and stuff, when i install them they dont work, waht should i do?
First do a factory reset from our technical help section, to see if you can avoid a reinstall. I know it's a lot of work sometimes but I would start over with a fresh install of Sims 3 if that happened to me.

I just bought a whole bunch of expansions, and I was wondering in what order I add the Hidden Springs expansion pack? - It doesn't even mention it on here!O_o
Hidden Springs is a World and you don't need to install those in any particular order as far as I know.

When I installed the sims 3 base game, the first few times I played it the game kept deleting my saves. It works fine now (I have played it millions of times since then)and I have the sims 3 university life. I want to install it but I'm worried that it might delete my data like the base game did at first. Will it be ok to install?

everythning is different im so confused right now.
Should I install them in order, or can I just do it randomly
I'd just install them in the order they came to prevent any problems and give you less trouble than doing it randomly. I'd be asking myself if I got Generations in yet if I did that one first, remembering 11 EPs and what ones have been done yet is annoying so a set list should make the process simpler.

Hi there, I am about to install all of the above games in order, which will hopefully go fine, but I also have some game content packages, "store updates"
Can I install these too? or would you recommend I don't? or if I can, do I do it at any certain point (like after all the above installs, or after a certain one)

Thanks in advance.

I don't understand. This board has so many conflicting messages. Some say it matters what order you install the Eps/Sps, while others say it doesn't matter, and it's fine to install earlier EPs over later ones. I'm really confused. Does it matter which order you install the EPs/SPs or not?

ok I was going right along following your install process and just finished installing Seasons. I see the next one up "should be University life and then Island Paradise.
Either they were not out when you wrote this OR your missing a couple.
70s 80s 90s stuff is not listed nor is Movie stuff. Can some one tell me before I mess it all up and have to reinstall
Thank you Kindly

I've installed the Sims 3 base game and University Life. I've played it lots of times. But when I installed Ambitions and updated it, the game won't work. Should I have updated it when I installed Ambitions or not?

I have supernaturals, then pets, then the world hidden springs, I just got generations and am amazon downloading it. Do I have to uninstall the others to make it work?

do I have to have all those to install the ones I want to install?
you don't have to install everything if you don't want to. Just make sure to install them in order.

How about the Monte Vista?
Monte Vista is store content not an expansion pack. Store Content is usually safe to start installing once you are done with everything else and fully patched up.

I'm trying to install Sims 3 Late Night, Pets, and high end loft stuff onto my mac, I already have the base game installed and when trying to install the expansion packs I have my computer says that I need to find where I installed the base game before I can install the expansions... How do I get them to install?
Do you know where you installed the base game? Is it on the computer under applications or is it on an external?

Just an FYI - EA informed me that you do NOT have to install the games in order anymore. They fixed that issue with a patch a while back. :) WAHOO!

Can my daughter use and run my Sims3 games if she only has the pets expansion? When she logs into her account from the play/update/upload/ etc screen will it boot her for using games that aren't registered under her account?

Hello Carl! (Or any particular person or admin)
I already have the base game, katy perry sweet treats, into the future, pets, supernatural, seasons, university life, and island paradise (not in that order). I just got Late Night and would now like to install that, but it continues to freeze on twelve seconds remaining (macintosh computer system). Is there any way to fix this without reinstalling everything?(My favorite, university life, was a gift from a friend and it got stolen :[)

Hey guys, I'm really worried about installing the Generations expansion pack only because I've done it twice before and I get an error message when I try to open up Sims. So what should I do, Should I go on and install the rest of them and then open up the game or what?

I have installed my sims 3 expansion packs up to generations, but I recently bought pets. I have a mac computer, and I was wondering if I have to uninstall my games in order up to where pets should go? Or can I just install pets despite being made before generations/seasons etc.

Is it okay?
