Re: Any way to stop Epic Games from launching The Sims 4
@Jasiek22 You should be able to play Sims 4 without signing into the Epic launcher, unless something has changed recently. But you may need to do a clean uninstall and reinstall of Sims 4 and the EA App. I wrote out instructions here in case it helps:
Whether or not you use the guide, make sure to rename the Sims 4 folder in Documents > Electronic Arts to something that doesn't include "Sims 4" so Revo won't flag it for removal.
Reinstall the EA App, then install Sims 4 through the App, and you should be able to avoid using Epic at all. If that's not the case, let me know; I'd like to hear if this doesn't work properly anymore. If that is the case, you'll just need to sign out of your Epic account and into your sister's before launching Sims 4.
