Im trying to open word, powerpoint, and excel but none of them will open. As soon as I do, they pop up in the dock, then they disappear and are replaced with the Microsoft Office Setup Assistant. It asks me to participate in the Customer Experience Improvement Program, I can select yes or no, then continue, but when I click finish it opens the update and nothing happens. I thought maybe there was an update, but there wasn't... So its not opening, what do i do?
