Installation Failed: Administrator Privileges

Hello All!

I am trying to install the new InDesign CC (2014) trial but Installation Failed appears immediately when I click Try with the reasoning "Administrator privileges are required to install. Please retry, or cancel to install later". I don't know why it keeps giving me this message because I am on the Admin account for my laptop and I logged in with that Admin login information when Application Manager tried to start the download. When I press Retry nothing happens or changes.

I am using a Mac with a recently installed OS X Mavericks so I don't know if there is some new setting that I have to change in order for it to work? I am stuck
