Only applicable to the 32-bit version of the game
If you are suffering from one of the Disc Authorization Failure error messages with The Sims 3 it could be for a few different reasons.
Disc Authorization Failure – no game disc found! Please insert The Sims 3 disc before proceeding.
- your superdrive may be faulty. Check other CDs and DVDs in the drive to see if they work.
- give the disc a good clean. If it is scratched beyond repair follow the steps below for playing using Origin.
- use Disk Utility (Applications > Utilities > Disk Utility) to verify and repair Permissions (only possible in OS X up to and including Yosemite, 10.10). Wouldn’t hurt to verify and repair the hard disk too whilst you’re there (thank you to MicronautDoc4 for pointing out this glaringly obvious omission on my part 😉 ).
- have you just upgraded your Operating System? If so maybe something corrupted in the install. Reinstall the OS.
Disc Authorization Failure – we are unable to verify that your disc is a valid copy of The Sims 3. Please contact customer service.
- make sure you’re not using a pirated copy of the game.
- this problem may be CC related. Move your Sims 3 folder (Documents > Electronic Arts > The Sims 3) onto your desktop and restart your game. A new Sims 3 folder will be generated. If your game now loads the problem is in your old game folder, most likely erroneous CC. Add your CC back in to your game bit by bit until the error appears again. You will then know which piece of CC is causing the problem.
(This problem also seems to be extremely common for those who have updated to OS X El Capitan)
The easiest way round these error messages is to play the game using a digital copy:
- Download and install Origin.
- Log in using your Sims 3 details.
- Register all your Sims 3 games under your Origin ID using the product codes that came with your disc copies (instructions on how to register product codes here). If you can’t find these, and the game is still installed on your Mac go here for instructions on how to find the codes using Terminal.
- Now quit Origin and uninstall the most recent EP/SP (most recent by release date) you have using the game Uninstaller found in Applications > The Sims 3. You also need to delete the hidden files for the EP/SP that the uninstaller doesn’t get rid of. For help on finding the hidden files and/or if you’re having problems uninstalling an Expansion or Stuff Pack using the Uninstaller, please read this guide on uninstalling it manually.
- Open Origin, download and install the EP/SP you just uninstalled.
- Your game should now work. Open the game using the usual game icon, you shouldn’t need to open Origin to play and you do not need to use the disc anymore.
- In the unlikely event that you’re still getting the error, updating with the digital version of the patch should resolve it. You can find instructions and links here. If it still doesn’t work then try uninstalling and reinstalling the entire game, including EPs and SPs, and installing the digital versions.
- If you are getting an error message stating that the code has already been registered when trying to redeem the code, make sure you are signed in using the EA/Origin account details you originally registered the disc copies of the game to. If you’re still not able to redeem the code then contact EA customer support – http://help.ea.com/en/contact-us/new/
