Can't launch the game

bambamz1310  If you use any apps with overlays, for example Steam or Discord, please shut them down before trying to open Sims 4.

If that doesn't help, please force the game to launch in windowed mode.  Open Options.ini, in Documents > Electronic Arts > The Sims 4, search for fullscreen , and set it to 0 (zero).

If that doesn't help either, please provide a dxdiag.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
