Electronic Arts has announced that The Sims 4 will drop support for 32bit operating systems in June 2019. Now while the main branch will be only supporting 64bit systems in June 2019 and onwards, PC gamers that still game on 32bit systems will be able to download a legacy version for it.
As EA noted:
“We regularly evaluate our technologies, and to continue growing, improving, and optimizing the game, we have made the decision to retire 32-bit support. If you are a PC player who cannot update to a 64-bit OS, The Sims 4: Legacy Edition will be made available to you.”
The Sims 4: Legacy Edition will be available for download in June 2019 and as you may have guessed, this particular version will not receive any more content or bug fixes. The Gallery, game banners, and social integrations will be disabled, and the Legacy Edition will not display or allow any purchases of content released after February 2019.
Last but not least, players will be able to purchase and play all Stuff, Game and Expansion packs released between September 2, 2014 and February 26, 2019. As for mods, it will be up to the custom content or mod developer to decide to support their custom content for both The Sims 4 and The Sims 4: Legacy Edition.
