@amybabyxo541 Does your Mac run Catalina? If so, that's the issue: Sims 3 is a 32-bit app, and Catalina is 64-bit only. There's no way around this issue. However, EA has announced a 64-bit version of Sims 3 for macOS, to be released (hopefully) some time this year; given the current situation and the latest news from Apple, delays are kind of inevitable. Here's the full announcement, and the latest update on the project:

In the interim, your only options are to play on another computer, to install Windows on your Mac (via Bootcamp or Parallels), or to install Mojave on an external hard drive or USB and boot into that when you want to play. For the second option, you'd need enough drive space to devote to Windows and the game; for the third, you'd need at least temporary access to a Mac running Mojave or earlier. Let me know whether you'd like more information about either of these options.
If you'd rather not wait for the update, you can request an automatic refund instead:
