I had a Microsoft Office Professional Plus 2016 installation on a Windows 10 PC. I later installed a Microsoft Office 365 ProPlus 2016 on the same PC, using a license from the company I work for.

When I open say Excel, I see the Microsoft Office Professional Plus 2016 version, as I can't see the new features specific to the 365 version, so I guess that although I can see both installations in Add and Remove programs, I can only use the first installation (or license?).

Is there a way to switch which version of Office I run? Could I uninstall the Professional Plus 2016 instalation and transfer the licence to another PC? how?


  • Which features exactly are unique to Office 365? You can’t have two versions of Office that are the same build (i.e the current version aka 2016) on a system – Ramhound Nov 4 '17 at 11:50
  • For example, the option "Insert Icon" in Powerpoint on 365. it is available in the O365 version but not in the Professional Plus. In "add and remove programs" I can see both versions – Roberto Nov 4 '17 at 12:11

Looks like completely uninstalling Microsoft Office Professional Plus 2016 lets the other version show up. I can see now the O365 specific options.
