Since I'm getting ready to install my new game, I thought I'd post a refresher on how to take your mods/cc out before installing. I got these from 3 different simmers on the S3 exchange.
1) The other thing is, there were bound to be issues with certain content when World Adventures came out, this happened back when University came out. Its mostly because it was just the first EP. This time around we shouldn't see those issues. Like Jaghar said, mods that change game behavior and text will have to be taken out, and you will have to check where you got them for updates. Some updates may take only a few hours after the creator gets Ambitions or the patch, others could take some days, and then you may also run into some mods that won't be updated, thats just how CC works.
Though, it is recommended to take out your Mods folder, the Resource.cfg file, and the d3dx9_31.dll file before you install the game or patch. Stuff installed though the launcher shouldn't be a problem, and store content won't have any issues at all.
2) Here is what you need to do.
First cut and paste your mods folder onto your desktop.
Second disable CC via the launcher.
Then you can install Ambitions.
Then you can add the mods folder and re-enable the CC via the launcher.
*Note some mods may need to be updated with Ambitions*
3) Instructions for safe patching (which includes adding EPs and SPs):
www.modthesims.info/wiki.php?title=Game_Hel...:TS3_Patching:Before_You_Begin If you use gameplay mods, you should NOT simply replace them after updating. Every patch/EP/SP necessarily breaks a lot of mods... because mods make changes to game code, and game updates change the code.
So with gameplay mods, remove them before installing the EP, and then look for updated versions (wherever you got the original mod). It may take a few days for modders to update their mods.
Large mods that do a lot of things will DEFINITELY need to be updated. Smaller mods MIGHT be OK, but if you're not finding updates for em, you should put them back one at a time and test them to make sure they're still working.
BTW, "regular" CC like hair, clothes, and objects CAN also break or cause problems because of an EP (or SP or patch), if the update changes how the game handles those objects. That's what happened with WA that caused so much trouble (the "blue lot bug").
So it is definitely advised to remove ALL CC before updating, and then try playing the game before putting back ANY CC. That way, if you have problems after replacing the CC, you'll know it was CC that caused it, and you can start trying to figure out what the culprit was
OK, now that we have that out of the way, Puddin mentioned this in another thread, but I'll copy & paste the comments directly from the latest update:
Game Update for 1.12/2.7/3.3
POSTED ON 05/28/10 05:34 PM
Players who play The Sims 3 with game modifications can now create a folder in which to place their game modifications. The folder should be located here:
C:\Documents and Settings\YourComputer\My Documents\Electronic Arts\The Sims 3\Mods
When Mods are placed in the official Mod folder, a notification will appear to remind players that Mods are installed.
Placing Mod packages into the Mod folder is an officially sanctioned way to bypass assembly signing verification. The Resource.cfg file must be placed in this folder in order for the modifications to work correctly.
When Mods are installed that are incompatible, the player will receive a message notifying them of the error.
Additional bug fixes to existing features
