What Prevents Sims 4 from Launching?

After going through some basic troubleshooting instructions, we came to the conclusion that the following are some of the most prominent reasons behind the occurrence of this issue.

  • Outdated Device Drivers: If the drivers on your computer haven’t been updated in a while, it might be a good idea to check for any available updates and apply them to your computer. Sometimes, outdated drivers can prevent games such as Sims 4 from launching properly.
  • Cache Files: Like all games, Sims 4 also caches important data to reduce loading times and to improve its overall feedback. However, in some cases, if this cache has been corrupted, you might run into the Sims 4 not opening issue. The best thing to do in that case is to just clear out the cached data so that it can be regenerated by the game automatically.
  • Origin In-game: It is possible that you might have enabled the Origin In-game feature which can sometimes hinder the launch of origin games. Therefore, it is recommended to turn this feature off using the guide below.
  • Faulty Mods: If you running the game with mods, it is entirely possible that one of the mods has either malfunctioned or it doesn’t work well with another installed mod. Therefore, Mods can also prevent Sims 4 from launching.
  • Firewall/Antivirus Restrictions: Sometimes, as a false positive, the default Windows Defender or a third-party antivirus can prevent the game from launching and running on your computer. Therefore, it is recommended to check whether this is what is preventing Sims 4 from launching.
  • Background Applications: There is a chance that a background application is causing the Sims 4 not opening issue on your computer by preventing you from being able to properly launch it. Therefore, as indicated in the methods below, check and identify if a background application is causing this issue.
