Using Product Keys (Activating Windows and MS Office)

Okay, the first question was answered but the 2nd one is a bit unclear based on your suggestion. So you meant to say that you need to uninstall the current MS office 2019 Pro and then install the MS Office 2016 Pro then using my newly bought product key to activate it?

 

Office 2019

Only supported on Win10. Sorry, 8.1 users, only 4 years old, gotta go.

Spoiler Office 2019
Last year at Ignite, we announced Office 2019 – the next perpetual version of Office that includes apps (including Word, Excel, PowerPoint, and Outlook, and Skype for Business) and servers (including Exchange, SharePoint, and Skype for Business). Today we’re pleased to share the following updates:

• Office 2019 will ship in H2 of 2018. Previews of the new apps and servers will start shipping in the second quarter of 2018.
• Office 2019 apps will be supported on:
  • Any supported Windows 10 SAC release
  • Windows 10 Enterprise LTSC 2018
  • The next LTSC release of Windows Server
• The Office 2019 client apps will be released with Click-to-Run installation technology only. We will not provide MSI as a deployment methodology for Office 2019 clients. We will continue to provide MSI for Office Server products.
