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 friend installed TS3 Pets on her laptop awhile back, and she has the serial number in the box. Her laptop broke a while back with the game still installed. She said I can have the game back(cause i miss it haha) so if I have the game disc can I install it on my laptop or do you have to uninstall it first on hers?

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.

I just purchased the Sims 3 into the future and im installing it on Mac ive installed latenight,seasons,pets,generations and Island paradise which also had the same problem but i solved it but since the sims 3 back into the future is a new expansion pack nobody had left a message on google about how to install it, whenever i try installing it it says ''You must have the sims 3 installed' but i do! and i tried to install it in Desktop where the rest of my sims are in!

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?

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.

Also, make sure that in your Sims 3 launcher you are going into the Expansions tab and check marking those which you would like included in your game.

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?

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!

How about installing Seasons; 70s,80s & 90s stuff and University Life ? How should i install them if i have all extensions ?
And one more question, for instance if i have :
The Sims 3 Base Game
The Sims 3 World Adventures Expansion Pack
The Sims 3 High End Loft Stuff
The Sims 3 Ambitions Expansion Pack
And i won't install fast lane and late night and then install Pets amd Supernatural will the game work correctly ?

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?

You forgot about the 70s 80s and 90s stuff pack. :)
25th October 2013 8:12pm
GabiOpal says...
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

those are stuff packs. they said it doesn't matter what order you install stuff packs in, but i would do them before the expansions
23rd July 2014 12:28am
Christopher says...
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.

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 :[)

Hi! So I purchased the Sims 3 a few years back, played it on a different laptop but that laptop bit the dust. I now have a new computer, but whenever I try to install the game it all goes smooth right up until the very end. It always gets snagged on one specific file, and no matter what I try it just won't go past that point. I'm not very adept with computers, and I was just wondering if there was any other way I could install the game, and understand how to do it? Thanks :)

Hi, I've been having many error 12 problems with my sim games so I thought I would reinstall them all in order, every game up until Generations gives me a patch update but after that I don't get any, is this normal? I've heard the Generation game has bugs and I was wondering if this is why? If anyone knows any advice it would be much appreciated!!! Thanks in advance :D

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.

How do I make a program not run so I can run supernatural? I got it today and have been trying for 2 hours to get it on
What do you mean? What program don't you want to run?

Katy says...
Hi. If i have Sims 3 plus Season hard disc with Late Night,Generation and Paradise Island how I can install those EP?
Sorry to bother you about this thing.(Sorry for my spelling, i'm from Europa)

Just install them like normal. You will need to use your Island Paradise disc to play the game though.

i installed sims 3 base game from origin.i try to install the rest but it says i should update the base do i do that if i already update like a million times. need help also do the rest of the sims 3 games go in one folder with the base game or do they have seperate folders.
Did you load up the launcher and install the patch in between each installation of EP/SP? On my computer I use Origin but I specifically don't have it download to the origin folder - either way it still creates a single Program file folder for each EP/SP.

I am currently working on a total uninstall/reinstall, AGAIN. This is more a failure of my pc and my game play but since I have corrupted files felt it needed to be done. For those of you having difficulties, the easiest way to uninstall is to use an unistaller. I personally use Revo, which is free, and has been recommended by the techies I talked to at EA. It does it all for you including getting rid of registry items. When you reinstall, update between each install if possible. Reinstall in order just to make sure it all works right. Installing from disc is faster but sometimes your disc might be dirty, scratched, or whatever and your pc can't read it. If you ordered your games from Origin you can reload them from Origin. If they were not purchased from Origin you might not be able to do this. I have two stuff packs that were gifts and Origin does not recognize them on my pc.

I have a problem here.. When I try to install the Supernatural expansion pack, or actually all the other packs except Late Night, and I try to start the game, it said "Disc Authorization Failure". Anybody knows how to deal with this? It worked fine before I install the packs, but now I can't play Sims 3 at all.

Make sure you are inserting your latest disk.
For example i own:
Sims 3 base game
Late night
University life.
To play the game with all installed ep's, I would use the sims 3 university life disk.

...about that...I just downloaded the sims 3 island paradise for mac and my game content doesn't show up. it says I downloaded it successfully, but when I try to play it (it's my latest expansion) the game says I need seasons to play...maybe I did the order of download wrong? here is how I did it:
sims 3 base
sims 3 world adventures
sims 3 generations
sims 3 seasons
sims 3 pets
sims 3 island paradise.

Any feedback would be nice..also, how do I re-install through origin in case that's the only way to fix this? thanks so much

Kate says...
If you're still having an issue and you have the disks, try registering the disks through This will automatically add the digital version to your Origins account for free. Then you can use the digital version through Origin rather than having to use the disk.
