Re: Sims 3 expansion CD keys

@Chloe20039  Yes, you can find your CD keys within your computer's registry.  Look in these two locations:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Electronic Arts\Sims(Steam)
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Sims(Steam

In each location, you'll see a number of files, one with a 20-character code that's the CD key you need to use.  I actually don't remember where the key is located between these two (sorry), and I'm not in front of my main Sims 3 install at the moment, but if you can't find the keys, just let me know and I'll grab a couple screenshots.

@roberta591  This is for Sims 3, not Sims 4, so there's no requirement to link Steam and Origin accounts.
