Say goodbye to the 32-bit version of The Sims 4.
The Sims 4

In 2019, Electronic Arts threw a bone to those still running on 32-bit versions of operating systems when they released The Sims 4: Legacy Edition. This was a 32-bit version of the long-running life-sim game that will soon be going away for good. On December 12, EA will pull the plug on The Sims 4: Legacy Edition, meaning that those still playing it will either need to upgrade or go elsewhere.

The silver lining here is that if you are still playing on Legacy Edition and are capable of upgrading to the regular version of The Sims 4, your saves should come with you. Electronic Arts and Maxis have provided what steps you will need to take in order to move from the Legacy Edition to the regular version of The Sims 4.

CAN I TRANSFER MY SAVE FILES?
Yes. If you update your computer to meet our latest system requirements, you can launch The Sims 4 as normal. Once you have updated to the full version of the game, you can transfer your save files using the steps below.
  1. Go to your Documents.
  2. Open Electronic Arts.
  3. Copy the folder titled The Sims 4 Legacy Edition.
  4. Transfer the file to the same folder (Documents/Electronic Arts) on your new computer, and change the title to The Sims 4.
  5. Launch the game.‚Äč
Obviously, in order to make this move at all you will need to move from a 32-bit operating system to a 64-bit operating system.
