@noahandsims Are you trying to install Sims 3 through Origin or the EA App? As far as I've seen, the EA App doesn't even offer the 32-bit version of Sims 3, but that may have changed recently.
At any rate, even though you're seeing a different error, this is the master thread for the missing 64-bit entitlements:
You'll need to contact EA customer support and ask them to add the entitlements for the base game and any packs you own. I would strongly recommend using live chat rather than email. If you don't see the option, try this link:
Make sure you're signed into an EA site (this one is fine) before clicking the link and that the location in the lower-right corner of the browser window is set to U.S. or U.K.
And if the support rep doesn't understand what you're asking, feel free to link the above master thread for more information.
I wanted to install it through EA app and when i saw the Sims 3 that EA sells, it tells that the game can only work with a MacOS supporting 32bits apps. I will try to contact them. Thank you for your help !
