okay so what happened is i bought my sims 3 expansion packs, world adventures, generations, university life and seasons and i downloaded it onto my old computer. i can not find the disc or games anywhere. i’m wondering if there is anyway i can find my codes for them on my computer since they are disc run games instead of on origin and redeem them onto origin on my new computer. thanks and happy gaming

@Guv1372 Yes, you should be able to find your codes on your old computer. Here's how:
Windows: https://sims3.crinrict.com/en/2013/09/how-to-find-your-serial-number.html
macOS: https://bluebellflora.com/finding-your-serial-key-using-terminal/
You can still register them in Origin, as long as you haven't already done so. If you created a Sims 3 Store account and added your content there, that would also count as registering your codes, since the store and Origin share information. In that case, you'd only need to login to Origin using the same email and password you used on the store site.
