Re: Sims won't open
@JazzieThuqqinz Your'e right, you don't need the Legacy Edition. Are you trying to launch Sims 4 from the shortcut on the desktop? If the shortcut points to TS4.exe (the .exe for the Legacy Edition), that might be the issue, although usually Origin calls the correct .exe anyway. Still, try running Origin as an admin but launching Sims 4 through the Play button within Origin.
You can also try disabling Origin in-game. There's a global setting, accessible by hovering over your username and selecting Application Settings > Origin in-game; and a Sims 4-specific setting, accessible by right-clicking on the game icon in Origin and selecting Game Properties.
If these steps don't help, temporarily disable any antivirus/firewall you have. If it works, you can add exceptions for Origin.exe and TS4_x64.exe.
