In this tutorial, we will be going over how to apply batch fixes to Create-a-Sim and Build/Buy mode.
Please be sure to READ CAREFULLY before you run a batch fix.
If you have any questions, feel free to ask and I will do my best to assist you.
So, let’s get started!

What You Need:
- Sims 4 Studio (*You must register for the site.)
Step 1
Install Sims 4 Studio!
If you are unsure on how to install S4S please read this guide here: Learning Your Tools: S4S
In the “Learning Your Tools: Sims4Studio” guide I will walk you through the install process and setting up the program for first-time use.
Step 2
Now that you have Sims 4 Studio installed, launch the program.
On the top navigation panel go to: Tools > Content Management > Batch Fixes
You will now see three options listed under Batch Fixes: CAS, Objects, and Misc.
These are the categories of fixes currently available for The Sims 4.
Let’s go over each of them, and their function.
NOTE: Even if you do not own one of the packs mentioned in the batch fix, run it anyways.
As the game still makes base game edits to items for other packs.
(example: Pets patch will fix missing slots and issues with many items even if you do not own pets.)

Step 3
Only run the batch fixes in RED if you are 100% sure you want to use those items.
NOTE: If you do happen to run a batch fix on something you did not want to change. There is a backup of the .package files that were changed in: Documents\Sims 4 Studio\Batch Fixes
If you have a lot of custom content installed the batch fix process can take quite some time. Just wait until it is finished.
