I am going to get Office 2016 for my Mac and I currently have Office 2011 installed on it. Is it okay to leave Office 2011 on my Mac if I install 2016 or do I need to delete Office 2011 before I install 2016? Is it okay to have both versions installed at once? I know there is a support document on the Microsoft website that shows you the steps to deleting 2011 but I don't really want to go through those steps if I don't have to. --- Post Merged, Feb 25, 2016 --- I was doing some research, If I install Office 2016 will it prompt me during installation to delete Office 2011?
