Installation of Office 365 on 2008 Macbook with OS -X 10.6 failed I was installing Office 365 on 2008 Macbook with OS X 10.6  and about half way through the installation a pop-up said to close Safari to continue installation. When I did, I received another pop up that installation failed. Was I suppose to X out of Safari which is what I did?
You needed to quit Safari "⌘+Q", "X-ing" out of safari only closes the window, not the program.
