Patch 1.70 is not a content update. It contains no bug fixes, new features, or Store fixes.
Instead, version 1.70 is strictly a launcher compatibility patch. EA released it to replace the old Origin thumbprint with the new EA App authentication system. If you are playing through Steam or a disc installation (without the EA App), you will most likely remain on Patch 1.67.
Unlike older patches, EA does not offer an official 1.70 super-patcher. However, some third-party archives keep it.
⚠️ Warning: Only use trusted sources. Corrupt patches break your game.
If you absolutely need the standalone file (e.g., for offline installs), search for:
Sims3_1.70.84.024001_from_1.67.2.024001.exe
from reputable Sims community sites like Mod The Sims or Nraas Wiki. The Sims 3 Patch 1.70 Download
Yes, but only if you own the game digitally.
While Patch 1.70 does not add new content (no worlds, no objects, no traits), it dramatically improves stability on modern hardware. The reduction in Error Code 12 and the ability to recognize RTX 30-series and 40-series graphics cards breathe new life into a 15-year-old game.
However, be prepared to spend 30 minutes tweaking your GraphicsRules.sgr file and reinstalling your Nraas mods. A vanilla install of Patch 1.70 is still buggy; a modded install of Patch 1.70 is a masterpiece.

Checksum (for safety): Always verify the file size is roughly 1.4 GB. If the file you downloaded is 10 MB, it is a virus. Delete it immediately.
Patch 1.70 deletes the Resource.cfg file if it exists. You must re-add the Mods folder setup.
If you own The Sims 3 on Steam, Patch 1.70 is mandatory.
After installing patch 1.70, do this:
✅ Delete scriptCache.package – Located in Documents\Electronic Arts\The Sims 3. Delete:
