Re: Sims 3 pets i can't find my registration code in steam
@csyntichakis I'm actually not sure whether the CD key will show up in your computer's registry, but please look there. Hit Windows key-R and enter "regedit" without quotes. Expand these folders, in order:
HKEY_LOCAL_MACHINE > Software > WOW6432Node > Electronic Arts > Sims(Steam) > The Sims 3
Click on the "ergc" folder, and under "Data," you might see a 20-character code, which would be the CD key for the base game. That's at least where the code would have been before Steam stopped showing the base game CD keys as well as keys for packs bought with the base game.
If this doesn't work, please let me know, and I'll flag this issue to see whether there's anything else you can do about it.
