Uninstall Microsoft 365 and Reinstall Your Licensed Office
Remove the conflicting Microsoft 365 trial or preinstalled software and cleanly reinstall your purchased Office version from your Microsoft account.
When a new computer comes with a preinstalled Microsoft 365 trial, it can take over default file associations and launch instead of your perpetual Office license. While multiple versions can technically coexist, it is highly recommended to remove the unwanted version to avoid activation prompts and conflicts.
Navigate to your system's settings and open the 'Apps and Features' or 'Add or Remove Programs' menu.
Scroll through the list of installed programs, locate the 'Microsoft 365 Family' trial or installation, and click 'Uninstall'. Restart your computer once the uninstallation is complete.
Open a web browser and navigate to https://office.com/myaccount. Sign in using the exact Microsoft account associated with your Office 2016 or 2019 purchase.
Locate your purchased Office license in your account dashboard and click 'Install' to download and setup the correct perpetual version.

Frequently Asked Questions
Can I have Office 2019 and Microsoft 365 installed at the same time?
Yes, multiple versions of Office can technically be installed on the same computer. However, this often causes file association conflicts where documents open in the Microsoft 365 trial instead of your licensed Office 2019 version. Removing the unwanted version is recommended.
Why does Word ask me to subscribe to Microsoft 365 when I own Office 2016?
This usually happens because a preinstalled trial version of Microsoft 365 on your computer has taken over the default file associations. Uninstalling the trial and reinstalling Office 2016 using your Microsoft account resolves this issue.
Where can I download my purchased version of Office?
You can download your licensed perpetual version (such as Office 2016 or 2019) by logging into https://office.com/myaccount with the Microsoft account you used during the initial purchase.
