Re: How Do I Install Sims 4 Without Origin
@KaelaIsMe You can't install Sims 4 without logging into an Origin account that owns it. When you're not sure how to find your Origin account, one approach is to enter every email address you have into the Origin login window and click "Forgot your password?" Any address associated with an Origin account should receive a password recovery email. Be sure to check your spam folder too.
If you don't get anywhere with this approach, you can contact EA customer support to ask for help.
