Officialy, Microsoft Office 2019 is only supported by Windows 10. It is not that Office 2019 is not supported by earlier versions of Windows but it is Microsoft’s way of forcing its users to upgrade to Windows 10.
If you try to install, you will get the notification below:
There are different ways to go about the installation on earlier versions of Windows, but I will explain the one I think is the simplest and direct.
The installation can be done by a third-party utility called Office 2013-2019 C2R Install.
Before I proceed, you will need an additional tool to mount the setup image drive.
Mount the Office 2019 Image file using any of the softwares above. The mounted file should show in your file explorer as CD Drive.
Get Microsoft Office 2019 Image file and activator below:
To perform the installation, Open Office C2R Install.
Then Select Install office.
If the Installation was done correctly, you should see something similar to the image below.
Office 2019 will ask you for a product key to activate the software.
