Re: EA app won't launch game just says download or manage
@Zmias1 Is your game still installed to the correct location? It's probably one of these, unless you changed it manually:
C:\Program Files\EA Games\The Sims 4
C:\Program Files (x86)\Origin Games\The Sims 4
If so, clicking Download probably won't reinstall the entire game. The EA App should instead verify the presence of the files and finish the install process, although I've had it redownload a few packs when I've tested. Regardless, the only way to fix this is to at least let the App try to download the game again.
