For over a decade, The Sims 3 has remained a beloved cornerstone of the life-simulation genre. While Maxis and EA have since moved on to The Sims 4 and even announced Project Rene, the modding community and a loyal fanbase keep the lights burning brightly in Sunset Valley. However, one technical hurdle consistently trips up returning players: The Sims 3 Patch 1.70 download.
If you own the game via Steam, the EA App, or retail discs, Patch 1.70 is the final stop on the update railroad. It is the culmination of years of bug fixes, performance tweaks, and compatibility patches designed to keep the game running on modern hardware (specifically Windows 10, Windows 11, and macOS Catalina or later).

In this guide, we will cover why you need this patch, how to download it safely, step-by-step installation instructions for every platform, common errors, and what to do if the automatic updater fails.
If you are launching The Sims 3 through the EA App (formerly Origin) on Windows, you have likely noticed your game version now reads 1.70. This patch can be confusing because the last major "super patch" was 1.67. So, what is 1.70, and do you need it? Wait for the process to complete
Here is everything you need to know about downloading and installing Patch 1.70.
This is the eternal debate in The Sims 3 community. Release Date: Late 2020 (Final Major Update) Platforms:
| Feature | Patch 1.70 (EA/Steam) | Patch 1.67 (Disc/Manual) | | :--- | :--- | :--- | | Launcher Requirement | Requires EA App or Steam | No launcher required (Can use TS3.exe directly) | | Mac 64-bit Support | Yes | No | | NoCD Mod Support | No (Game checks for disc/DRM) | Yes | | Store Content Fix | Yes (Fixed) | Yes (Fixed) | | Windows 11 Support | Official | Unofficial (Works but risky) |
Our advice: If you use a Mac, you must use Patch 1.70. If you use Windows and hate the EA App, stick with Patch 1.67. If you use Steam, you have no choice but to use 1.70.
Use this if your launcher says "Update Pending" but never moves.
