Xf Adsk64 Autocad 2016 Serial Number

My comment disappeared, so I am posting again. I downloaded a trial version of Autocad 2016,and tried all of the serial number strings suggested in your install procedure. With every attempt, a dialog box came up saying the serial number was not a valid serial number. Do you have any suggestions on how to get this to work?
