Perform an Online Repair and Update Office

Right-click on the Windows Start menu and select 'Apps and Features' from the list.
Scroll down the list of installed apps to locate your Microsoft Office product. Click on it and select the 'Modify' button.
When the repair prompt appears, select 'Online Repair' and then click 'Repair'. Follow the on-screen instructions until the process is fully complete.
Open an Office application such as Word or Excel. Navigate to 'File' > 'Account' (or 'Office Account').
Click on 'Update Options' and select 'Update Now'. Once the updates are installed, attempt to enter your product key again.

Frequently Asked Questions
Why does my Office 2019 activation window keep closing?
This behavior is typically caused by corrupted Office installation files, software conflicts, or outdated versions of the application failing to process the license validation.
What is the difference between Quick Repair and Online Repair?
Quick Repair attempts to fix corruption locally without an internet connection, while Online Repair completely reinstalls Office components by downloading fresh files from Microsoft's servers, making it much more effective for persistent errors.
Will running an Online Repair delete my Word documents or Excel files?
No, running a repair on Microsoft Office only fixes the program files. It will not delete, alter, or remove any of your personal documents, spreadsheets, or presentations.
