Fix One-Time Purchase License Error in Word and Excel
Question details
Users receive an Action Required message when attempting to use Word or Excel with a one-time purchase license on a machine with Microsoft 365 installed.
- Product
- Microsoft Word, Microsoft Excel
- Device & OS
- not provided
- Scenario
- Activating and using Office applications after downloading the installer from Microsoft365.com.
- Observed behavior
- An Action Required error message appears, preventing normal use of Word and Excel because the installed subscription version does not match the user's perpetual license type.
Verify your exact Microsoft Office license type by logging into your Microsoft account and checking the Services & Subscriptions section to confirm whether you own a Microsoft 365 subscription or a one-time perpetual license (like Office 2021).
Uninstall Microsoft 365 and Install the Perpetual Office Version
Remove the mismatched subscription applications and download the correct installer linked to your one-time purchase license.
A common cause of activation errors is having the Microsoft 365 subscription apps installed when your account only holds a one-time purchase license (e.g., Office Home & Student). These are different software versions, and a perpetual license key cannot activate Microsoft 365.
Click the Start menu, go to Settings, and select Apps (or Apps & features) to view your installed programs.
Scroll through the list to find 'Microsoft 365' or 'Office 365'. Click on it and select Uninstall, then follow the prompts to completely remove the software from your computer.
Open a web browser, navigate to account.microsoft.com, and sign in using the email address associated with your Office purchase.
Go to the Services & Subscriptions tab. Locate your specific one-time purchase product (such as Office 2021 or Office 2019) in the list and click the Install button to download the correct setup file.
Run the downloaded installer. Once the installation is complete, open Word or Excel and log in with your Microsoft account to activate the software automatically.

Frequently Asked Questions
Why does my one-time Office license say Action Required?
This occurs when your computer has Microsoft 365 applications installed, but your purchased license is for a perpetual version like Office 2019 or 2021. The subscription software cannot be activated using a perpetual key.
Will uninstalling Microsoft 365 delete my Word and Excel documents?
No, uninstalling the Microsoft 365 applications will not delete your personal files, documents, or spreadsheets. They remain safely stored on your local hard drive or in your OneDrive folder.
Where can I download the correct installer for my one-time purchase?
You can find the correct installer by logging into your Microsoft account, navigating to the Services & Subscriptions page, and clicking the install button located directly next to your purchased Office product.
Can I keep the Microsoft 365 apps and just enter my perpetual product key?
No, Microsoft 365 apps and one-time purchase apps use different underlying architectures. You must completely uninstall the Microsoft 365 suite before installing your perpetual Office version to avoid conflicts.
