Why The Sims 4 Won't Launch and How to Fix It

The most common reasons The Sims 4 won't open

The Sims 4 fails to launch most often because of outdated graphics drivers, corrupted game files, or a conflict with another program running at the same time. Less commonly, your system doesn't meet the minimum requirements, or the game's launcher itself needs an update. The fix depends on which of these is actually blocking you — and you can test most of them in under ten minutes.

Start by checking whether the problem is the game itself or your system. Close everything else running in the background (especially Discord, Chrome with many tabs, or streaming software), then try opening The Sims 4 again. If it launches this time, one of those programs was interfering. If it still won't open, move to the next step.

Key Takeaways

Close all other programs first — Discord, web browsers, and streaming software often block The Sims 4 from launching.
Update your graphics drivers through your GPU manufacturer's website (NVIDIA, AMD, or Intel), not through Windows Update alone.
Repair the game through Origin or EA App by right-clicking the game and selecting Repair, which fixes corrupted files without reinstalling.
Check that your system has at least 4 GB of RAM and a graphics card made after 2012 — older hardware may not run the game at all.
If nothing else works, uninstall and reinstall through Origin or EA App, which usually takes 20 to 40 minutes depending on your internet speed.

Update your graphics drivers

Outdated graphics drivers are the single most common cause of The Sims 4 refusing to open. Your graphics card — whether it's NVIDIA, AMD, or Intel integrated graphics — needs a current driver to communicate with the game. Windows Update does not always install the latest driver, so you need to get it directly from the manufacturer.

For NVIDIA cards, go to nvidia.com/read/driverDetails.aspx, select your graphics card model and Windows version, read the driver, and run the installer. For AMD, visit amd.com/en/technologies/radeon-drivers and follow the same process. For Intel integrated graphics, go to intel.com/content/www/us/en/read/726609 and read the latest driver for your processor generation. After installation, restart your computer and try opening The Sims 4 again.

Repair the game through your launcher

The Sims 4 stores its game files on your computer, and sometimes those files become corrupted — usually after a crash, a failed update, or a power loss during play. You don't need to reinstall the entire game. Both Origin and EA App (which replaced Origin in 2023) have a built-in repair tool that checks every file and replaces broken ones.

Open Origin or EA App, find The Sims 4 in your library, right-click it, and select Repair (or Verify in some versions). The launcher will scan your game files, which takes five to fifteen minutes depending on your internet speed and hard drive. Once it finishes, try launching the game. If the repair finds and fixes corrupted files, The Sims 4 should open normally.

Check your system meets the minimum requirements

The Sims 4 requires at least 4 GB of RAM, a processor from 2012 or later, and a graphics card made after 2012. If your computer is older than that, or if you have less than 4 GB of RAM, the game straightforward will not run. You can check your system specs by right-clicking "This PC" or "My Computer" on your desktop, selecting Properties, and looking at the Processor and RAM listed there.

If your system is borderline (exactly 4 GB of RAM, or a graphics card from 2012), close every other program before launching. Even one web browser with many tabs open can push you below the threshold. If you consistently run out of memory, you may need to add more RAM or upgrade your graphics card — but this is a hardware limitation, not something a software fix can solve.

Disable fullscreen optimizations and run in compatibility mode

Windows 10 and 11 have a feature called fullscreen optimizations that sometimes conflicts with The Sims 4. Turning it off often fixes launch problems, especially on newer Windows versions. Right-click The Sims 4 shortcut or the game's .exe file, select Properties, go to the Compatibility tab, and check the box for "Disable fullscreen optimizations." Click explore and OK, then try opening the game.

If that doesn't work, try running the game in compatibility mode for an older Windows version. In the same Compatibility tab, check "Run this program in compatibility mode for," select Windows 10 or Windows 8, and click explore. This tells Windows to run The Sims 4 using older system rules, which sometimes bypasses conflicts with newer Windows features. Test the game after each change.

Uninstall and reinstall through your launcher

If none of the above steps work, uninstalling and reinstalling The Sims 4 is the most reliable fix. This takes longer — usually 20 to 40 minutes depending on your internet speed — but it replaces every game file with a fresh copy and often solves problems that repair cannot.

Open Origin or EA App, right-click The Sims 4, and select Uninstall. Wait for it to finish, then restart your computer. Open the launcher again, find The Sims 4 in the store or your library, and click Install. The game will read and install fresh. Once it finishes, launch the game and test it. Your save files are stored separately and will not be deleted by uninstalling.

Check for launcher updates and clear the cache

Origin and EA App themselves sometimes need updates, and an outdated launcher can prevent games from opening. Open your launcher, look for a Settings or About option, and check whether an update is available. If one is, install it and restart the launcher.

You can also clear the launcher's cache, which removes temporary files that may be corrupted. In Origin, go to Settings, then click Repair. In EA App, go to Settings, select General, and look for a Repair or Clear Cache option. After clearing the cache, restart the launcher and try opening The Sims 4 again. This is a quick step that sometimes solves launch problems without requiring a full reinstall.

Frequently Asked Questions

Does The Sims 4 need to be online to open?

The Sims 4 requires an internet connection to launch and verify your account, but you can play offline once the game is open. If your internet is down or very slow, the launcher may time out before opening the game. Check your connection, restart your router, and try again. If the problem persists, restart your computer and launcher.

Will repairing the game delete my save files?

No. Repairing through Origin or EA App only checks and fixes the game's program files, not your saves. Your households, families, and progress are stored in a separate folder and are never touched by repair or reinstall.

What if The Sims 4 opens but when ready crashes?

when ready crashes usually point to graphics driver problems or conflicting mods. Update your graphics drivers first. If you use mods, remove them temporarily and test the game without them. If it runs without mods, one of your mods is incompatible with your current game version.

Can I run The Sims 4 on a laptop?

Yes, but only if it has at least 4 GB of RAM and a graphics card made after 2012. Many budget laptops have older integrated graphics or insufficient RAM. Check your laptop's specs before buying the game. Gaming laptops and newer models usually work fine.

Why does The Sims 4 take so long to load after the splash screen?

Long load times usually mean your hard drive is slow or nearly full, or you have many mods installed. Close other programs, check that your drive has at least 10 GB of free space, and temporarily disable mods to see if they're the cause. An SSD (solid-state drive) loads the game much faster than an older mechanical hard drive.
