Sims 4 error: Failed to launch game

robynamos  That's good to hear, at least, but I don't know whether uninstalling and reinstalling the game will help.  Before doing that, I'd suggest clearing Windows temp files, as described here:

It's also worth trying to play in a new admin Windows account.  Make it local, as in, don't link your Microsoft account or any email address.  Please also make sure the new account's username contains only letters found in the Roman alphabet: no special characters, no accents, nothing atypical at all.  You'll be able to (try to) launch Sims 4 without reinstalling anything.  Your saves and other user data won't be available, but that's fine for now and can be addressed later.

If that doesn't help, then yes, it's worth reinstalling the game.  But since you're going to go through the process anyway, I would suggest doing a clean uninstall of both Sims 4 and the EA App, as described in the accepted solution of this thread:

[CURRENT ISSUE] Sims 4 DLC shows as installed, won't load in-game | EA Forums - 11831673

Anchors aren't working on this site at the moment, so use ctrl-F to search for revo and jump there.

I would also use the new Windows account when reinstalling the App and the game.

I followed your instructions to the letter and even though I had to do the clean install of everything, I'm finally able to play my game!  So happy.  Thank you so much for the advice!

Hello,

I'm hoping someone can help me. I've been playing offline for awhile, however earlier this evening I finally got around to updating my mods and the Sims 4 game itself. As usually removed mods from folder and tried to launch the game. I got the message below (see screen shot). I cleared my cache, did appy recovery, and even repaired my game only to get the same message. Does anyone have any idea what's going on and how to fix it? Note: I was playing the game fine offline earlier today (3/22/25) and this didn't occur until I updated my game. 

After getting absolutely no help from EA I tried various suggested fixes from the internet. Ultimately I had to uninstall both the EA App and Sims 4, clear cache and history, and then reinstall. This seems to have resolved the issue. Albeit it appears I might have lost reward items. 

I have seen this posted elsewhere on the thread, so my apologies for a repetitive topic, but having read through the other posts and attempted to recreate the fixes suggested, I am having no luck. 

When I attempt to launch the Sims 4, I receive an error: "Failed to launch game. An error on our end cause the launch to fail. Try again a little later." When this happened in the past, it lasted for several months, rendering the game unplayable, and then one day poof it worked again. My wife played it 10 days ago with no issue, and then today, the same error is back again. 

So far I have attempted to manually update the EA app (no updates available); attempted to manually update The Sims 4 (no updates available); cleared the EA app cache (cleared, but made no difference). Within the EA launcher app, I attempted the "repair" option for the sims (under the "manage" option). However, despite a completed repair, I receive the same error. 

I've attached the DxDiag and I filed a report with EA, not sure how much good it will do. Thank you in advance to anyone who might be able to assist.

I'm unable to launch any EA game through the EA App. Every time I try to run a game, I receive this error:

"Your game failed to launch. An error on our end caused your launch to fail. Try again a little later."

Here's what I've tried so far:

Reinstalled EA App

Cleared EA App cache

Reinstalled the game

Repaired game files

Changed DNS / tried VPN

Logged in with another EA account

Unlinked and relinked EA with Steam

Tried launching directly from Steam

Even tried launching in offline mode – still no luck

The issue happened to one of my friends 10 days ago and started for me 2 days ago. We are 4 friends playing together — 2 of us are having this problem, the other 2 are not.

I had this same issue about a month ago and reinstalling the game fixed it temporarily, but now it came back and nothing works.

Since even offline mode doesn’t work, I believe the problem may be with my account data or the way EA App handles local licenses/cache. Please check and reset any possible corrupted cloud or account data.

Thanks in advance for your help.

This error has been around for more than a week and it really gets me frustrated. I tried every methods in every articles or forums I found but nothing helps. What do I supposed to do now, I really lost. Perhaps this will be my last product I bought from EA. Can even get to play the game you paid by your own money :/

I keep getting this error when I go click play. EA sims game says “failed to launch game. an error on our end caused the launch to fail. Try again a little later.” is anyone else having this issue? I removed my mods folder “repaired” my game and nothing. This is has been an issue for weeks atp. I have a MacBook btw. 

I've tried every fix on the internet and I still cannot get the game to open I just keep getting the error message " An error on our end caused the launch to fail. " PLEASE HELP from what ive seen online nothing has seem to resolve this issue.

I wanted to play today and I keep getting this message: Your Game Failed to Launch.  Error On Our End.

I tried to close the app and re-open it. It didn't work. I also tried to restart my computer. I also tried to run the EAUpdater.exe. and it said the app is already updated. 

I tried to repair the game but it goes up to 2% then it restarts at 0% and then I get a fail message.

I can't even go to help.ea to try to contact EA support as the page stays blank

Can anyone help, please?

Thank you!
