Game failing to launch. Windows flagging TS4_Launcher_x64.exe as Trojan
Hey everyone!
I was wondering if anyone else has the same issue as me since the newest sims update (21-7-2026). Basically what is happening for me is that I can no longer launch the game. I played the day before the update and had no issue whatsoever.
Whenever I try to launch the game, I get a notification in the EA app, saying: "Failed to launch game. An error on our end caused the launch to fail. Try again a little later." With that I also get a notification from Windows Security saying: "Part of this app has been blocked. Some features of EA may not work because we can't confirm who published TS4_Launcher_x64.exe that the app tried to load."
I looked at the properties of the sims, and the digital signature is gone. I tried repairing the game, which didn't work, and reinstalling both EA and the Sims in its entirety. Both did not fix my problem. I went on to check in powershell to see if the game truly wasn't signed, and indeed it wasn't.
I could turn off my smart app control, to see if that would allow me to launch the game, but I'd rather not do that for obvious reasons.
If there is anyone else who also has this issue, or may knows how to fix it, please let me know!

Hi all,
A targeted Windows-only update is rolling out now to resolve the digital signature issue preventing The Sims 4 from launching.
Since this fix only updates the launcher, your game version will not change and your mods/CC will be completely unaffected.
Thank you all for your patience while we got this sorted out!
