Cannot repair or uninstall game

I have star wars battlefront 2 on my computer, I am trying to uninstall it as I'm not playing it and it takes up a lot of space. When I try to uninstall it it says the game needs to be repaired. When I go into Origin and right click the game, even when running as administrator, I am not shown a repair option or an uninstall option. I even tried uninstalling Origin and it will not let me. I just want to get this game off my computer. Please help.
