when i try to launch the game i get a message that says that there is an error and that i have to reinstall the game. i've reinstalled it about three times now and the message still shows up and the game won't launch. i've seen some solutions for this issue but none of those have worked for me. help :(
Bird6402 Please try playing in a new admin Windows account. Make it local, as in, don't link it to your Microsoft account or any email address. (You can keep declining until you're asked some security questions instead.) You'll be able to at least try to launch the game without reinstalling anything.
If that doesn't help, please do a clean uninstall of Sims 4 and the EA App with Revo Uninstaller (the free version is fine). How to do so is covered in the accepted solution of this thread:

Don't uninstall Steam with Revo unless Sims 4 is your only Steam game, as removing Steam will also remove any games installed to the default Steam library.
When reinstalling Sims 4, create a new Steam library for it, as described here:
