Solution 1Recommended

Uninstall Microsoft 365 and Reinstall Office 2019

Remove the incorrect Microsoft 365 installation from your computer and manually reinstall the Office 2019 edition you originally purchased.

Sometimes Windows updates or pre-installed software can cause Microsoft 365 Apps to replace or overwrite a perpetual Office 2019 installation. Since these are separate licenses, the Microsoft 365 app will ask for a subscription you do not own.

1
Verify installed programs

Open the Windows Control Panel, select 'Programs', and then click 'Programs and Features'. Look for 'Microsoft 365' in the list of installed applications.

2
Uninstall Microsoft 365

Right-click on the Microsoft 365 entry in the programs list and select 'Uninstall'. Follow the on-screen prompts to completely remove it from your device.

3
Access your Microsoft Services account

Open a web browser and navigate to account.microsoft.com/services. Sign in using the exact Microsoft account you used when purchasing Office 2019.

4
Download and install Office 2019

Under the 'Purchased Products' section, locate your Office 2019 license. Click the 'Install' button and follow the instructions to download and set up the correct version of Office.

Check Multiple Accounts: If you do not see Office 2019 listed under 'Purchased Products', you may be logged into the wrong Microsoft account. Try signing in with any other email addresses you might have used at the time of purchase.

Frequently Asked Questions

Why did my computer change from Office 2019 to Microsoft 365 without my permission?

This typically happens when Windows installs a system update that includes the Microsoft 365 trial, or if a pre-installed version of Microsoft 365 on a new PC becomes active and masks your older perpetual installation.

Do I need to pay a subscription fee to keep using Office 2019?

No. Office 2019 is a perpetual license, meaning it is a one-time purchase. If you are being asked to pay for a subscription, it means the Microsoft 365 software is currently installed instead of your Office 2019 software.

What if my purchased Office 2019 license is completely missing from my account dashboard?

If you check account.microsoft.com/services and see nothing under 'Purchased Products', you are likely signed in with a different Microsoft account than the one used during the original transaction. Check all possible email addresses you own.
