And let me know whether it helps.  If not, what exactly do you need the launcher login for?  It doesn't serve any purpose in most cases.

Hello, I am having the same issue I need help with my account I can login into the sims 3 account but when I hit play in the launcher it keeps saying to register my account in when I attempt to put the code in for the registration it's telling me invalid. I've been having my account since December 20th, 2013. I've just recently downloaded to my computer I've been playing sims 4 but I wanted to play my sims 3 in now I can't. can someone please help?

@gg_sims3  I'm not sure what you're describing here.  Your screenshot shows the Main Menu, not the launcher, and signing in is not required in order to play.  It only enables a couple of online features (gifting, Simport), badge tracking, and the ability to buy Store items from within the game; you don't need to sign in if you have no interest in those features.  The Sims 3 launcher is the window you see when you click Play in the EA App, the one you'd used to install Store content.  If that Play button didn't work, you wouldn't get to the Main Menu.

At any rate, one reason the sign in might not work is that your password has special characters in it.  In that case, try changing the password to something with only letters and numbers.  Another possibility is that you've installed Sims 3 using a different account than the one you use on the Store site.  If that's the case, it explains the issue: the in-game login needs to match or the game won't accept it.

it was never fixed its 2024 and the live chat helpers dont even know how to help me

2024 and this still happens.

Thank you very much for your help.  I don't know which worked, but I changed my password (no special characters) and cleared the cache of both MS Edge and MS Internet Explorer.  I didn't even know IE still existed.

Thanks again.

its been two years and still nothing and now i cant even delete the app
