Warning: Some mods and custom content may contain bugs or errors. These are unofficial modifications to the game that do not go through the standard quality assurance process that official add-ons and content go through.

Click Documents in the sidebar to the left. Open the Electronic Arts folder. Open The Sims 3 folder.

The FrameworkSetup file will contain the necessary framework for your mods - a folder named Overrides, a folder named Packages, and a file named “Resource. cfg”. The Packages folder will already have two files in it (“nobuildsparkles. package” and “nointro. package”) so you’ll be able to check if your mods will work. If you start up your game and get no intro animation, nor any sparkles when placing walls or fences, everything is working. The “Resource. cfg” file may trigger some antivirus software programs. This is because it’s a “. cfg” file, not because it’s malware. The file is safe and necessary to install mods on The Sims 3. Very old versions of The Sims 3 (prior to the release of World Adventures and its patch) would have mods and content in the Program Files directory. This no longer works - do not attempt to place custom content in Program Files and do not use Monkey Bars or Helper Monkey to install your content.

Modthesims. info is a great website to download mods for all Sims games. Click “Sims 3” in the upper-left hand corner, then click on “Downloads”. (You can refine your search as needed on the Downloads pages. )

It’s recommended to only install one mod at a time, especially if the mods in question are core mods (i. e. , it alters a key method of how the game runs). Installing multiple mods at once can make it difficult to determine the cause if two of the mods turn out to be incompatible with each other.

You’ll usually be able to tell when a mod is conflicting with something - you’ll get bugs that make it difficult, if not impossible, to play (such as Sims constantly resetting themselves when attempting to perform an action), or the game just might not load at all.

Navigate to the Packages folder. Right-click a blank space in the folder. Click New. Click Folder. Type a name for the folder.

NRaas Overwatch, MasterController, and ErrorTrap work in tandem to catch errors or reset them.
