Game doesn't start

The game never worked

• Start Origin and the game as administrator
• Use ccleaner to clean your registry.
• Delete the Origin cache files.
• Check your hardware, esp. chkdsk, to make sure your hard drive doesn't have any issues
• Make sure your antivirus software/firewall are not blocking the connection. It's not always enough to create an exception especially if the program has already blicked the game. Check your firewall/antivirus software's manaul on how to proceed. Comodo Firewall seems to be notorious for blocking. Add the following programs to your exception list: authorizationUI, TS4.exe, Origin.exe
• Start the game in windowed mode. If the game runs, lower all settings and put it back to full-screen mode.
• Eliminate issues with Origin
• Deactivate Origin ingame
• Reinstall Origin and the game and make sure they are on the same drive, preferably c:
• Repair the game through Origin
• Clean Boot your PC
• Play in offline mode
• Make sure that you don't have programs that have a known conflict with Origin
• Update your graphics drivers.
• VPNs can lead to potential conflicts with the game
• Make sure your computer fulfills the requirements of the game.
• Make sure your Windows is updated
• Make sure the game is updated (Right-click on the Game in Origin and choose Search for Updates).
• Network Troubleshooting:
  • How can I reset the Hosts file back to the default?
  • How to flush DNS Cache for Windows

The game suddenly doesn't start anymore

On top of the things above you can also try this

• Reset your user files
• Deactivate newly installed programs
