Solution 1Recommended

Use the Official Office Uninstall Tool and Reinstall Office 2019

Completely remove all conflicting Microsoft 365 files using Microsoft's Support and Recovery Assistant before attempting to reinstall Office 2019.

When leftover files or registry keys from a previous Microsoft 365 installation remain on your system, they can conflict with the Office 2019 setup. This causes the newly installed apps to incorrectly recognize the subscription license instead of your perpetual license.

1
Download the Uninstall Tool

Download the Microsoft Office uninstall tool by navigating to https://aka.ms/SaRA-officeUninstallFromPC in your web browser.

2
Run the Uninstaller

Launch the downloaded executable to open the Support and Recovery Assistant. Follow the on-screen prompts and select all Office products, specifically any Microsoft 365 entries, to remove them completely.

3

Once the uninstallation process is finished, restart your computer to ensure all leftover temporary files and registry keys are cleared.

4

Frequently Asked Questions

Why does my Office 2019 say Microsoft 365?

This typically happens if your computer came with a pre-installed trial of Microsoft 365, or if leftover registry keys from a previous 365 installation force the new installation to recognize the subscription version instead of your perpetual 2019 license.

Can I have both Office 2019 and Microsoft 365 installed on the same computer?

Generally, no. Microsoft prevents installing different versions of Office (like a perpetual 2019 license and a 365 subscription) on the same computer simultaneously if they use the same Click-to-Run installation technology.

Will using the Microsoft uninstall tool delete my personal documents?

No, the Microsoft Support and Recovery Assistant (SaRA) only removes the Office application files, settings, and corrupted license keys. Your personal Word documents, Excel spreadsheets, and other files remain safe on your hard drive.
