Re: Sims 3 ERROR 16 HELP
@lmaoisa_ Please move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop. When you launch the game, a clean folder will spawn with no content. Don't add anything to it yet; just start a new save and see whether you get another Error 16. If the Sims 3 folder copies instead of moving, please say so.
If you do get another Error 16, please let me know what antivirus, if any, you use, and whether OneDrive is active and syncing the contents of Documents.
