Problem with app

Hi, I need help with ea desktop Origin. I have tried downloading and reinstalling it multiple times (at least seven times), but it still does not open.The Sims game is installed on my computer, but when I try to open it, it says that ea Desktop Origin is required to run the game, even though I have already installed it.I have also tried restarting my computer and running as administrator, but nothing works. I think there might be a technical issue preventing the launcher from opening.Can you please help me fix this so I can open EA Desktop Origin and my games?
