The Sims 3 patching sequence question

First of all, if you're installing via Origin, you'll automatically receive patch 1.69 and won't need to do any patching yourself. But you'll also get the mandatory Origin tie-in and the pack selector, so you might prefer to use your discs instead. To stay on 1.67, you'll need disc copies of all your packs, as well as a base game disc manufactured before September 2012. Otherwise, the base game install process will force you to download Origin and patch to 1.69, and a single digital install will do the same.

The launcher has always been unreliable with patching, but that's especially true when you're trying to go from an early base game disc version to 1.67 in one fell swoop. The best practice is to install the base game only, run the Super Patch, install your packs, and run the Super Patch again, just to be thorough. In fact, if you really want to make sure Origin doesn't interfere, here's the most effective way:

• (You've already uninstalled and cleaned your computer's registry, which would be the first step.)
  
• Uninstall Origin as well, if you have it on your computer.
  
• Download the Super Patch from here: https://forums.thesims.com/en_US/discussion/175477/official-ea-download-link-for-the-sims-3-cumulative-manual-update#latest
  
• Take your computer completely offline—turn off wifi or pull the ethernet cable.
  
• Now install the base game. You'll get an offer for the EA Download Manager to control your install. Say no. The EADM will do everything it can to update itself to Origin.
  
• Run the Super Patch, confirm that the launcher lists your patch level (in the lowe left corner) as 1.67, and launch the game.
  
• If it works, you can install your packs, again from disc. When you're done, you can run the Super Patch again, just to be thorough.
  
• When you're back online, the launcher may say you need to update. These are patches for the early packs, before the pack patches were bundled with the base game, and accepting them won't update you to 1.69.
