I have not redeemed them on the sims3 site either. I always just used the cd's, but my computer is newer than the games so the game won't even open if I install them with the discs. The ones that didn't work was Pets and Late Night.
Also, Origin CS said there was nothing that could be done.
@nekonaja The reason I asked what packs you own, not just the ones whose codes don't work but the others, is that it's sometimes possible to install via disc, as long as you're not playing via disc. If you own a pack that's newer (by the date EA released it) than Pets, you might be able to install Pets and Late Night using your discs, then install the newer pack from Origin, and play that way. This only works though if you own a pack that's newer than Pets.
The unknown error you were seeing isn't because you installed via disc, it's because Late Night needs extra help to get installed properly. If you'd like to try to get all your content installed, please list the other packs you own, and I'll try to help.
I own newer packs than pets. The packs I own are:
Island Paradise, Supernatural, Katy Perry stuff, University, Generations, Seasons, Town life stuff, Ambitions, High end loft stuff
@nekonaja Great, that might work. (Might.) Which packs, if any, do you have installed right now, and is the game currently running properly?
I installed all the packs I mentioned through Origin. And the game is running properly.
@nekonaja Okay, you could try installing Pets via disc, to see whether it works. If you get the disc authorization error, manually uninstall Island Paradise and reinstall it through Origin.
[Edit: These specific instructions are only for macOS. In Windows, sometimes installing via disc into an Origin-controlled install can make Origin recognize and load the disc-installed packs.]

You'd probably (unless you have a version of macOS older than El Capitan) also need to copy a folder from Ambitions into the folder for Island Paradise. The video in this thread shows how to do it:
Just try Pets first, because it's less complicated than installing Late Night. If you can't get it to work, you can use the manual uninstall guide to get rid of Pets.
I tried what you said on my computer, and it worked! Both of the games worked right away 🙂 Thank you so much!
@nekonaja Glad to hear it worked. And yeah, this was originally a Mac thread, but I probably still should have asked.
