- Product
- Microsoft Word 2016
- Device & OS
- not provided
- Scenario
- Reinstalling Microsoft Office Professional Plus 2016 and attempting to open existing Word documents.
- Observed behavior
- Microsoft Word fails to open files and re-entering the product key or restarting the computer does not resolve the problem.
Ensure you are logged into the correct Microsoft account that was originally used to purchase or activate Office 2016. Have your purchase confirmation details ready if you need to verify the license validity.
Verify Microsoft Account and License Activation
Office 2016 licenses are typically tied to your Microsoft account rather than a standalone product key. Verifying the account link often resolves post-reinstallation opening issues.
When reinstalling Office 2016, especially Office Professional Plus, entering a product key again can cause conflicts if the key is already linked to a digital Microsoft account. If Word fails to open but Excel works, it may be stuck in an activation loop or authentication error.
Go to the official Microsoft account website in your browser and sign in with the email address linked to your Office 2016 purchase.
Navigate to the 'Services & subscriptions' section to confirm your Office 2016 license is active and properly linked to your account.
Open Microsoft Word, click on 'File' > 'Account', and sign in with that exact Microsoft account to activate the software instead of using a product key.

Frequently Asked Questions
Why does Excel work but Word doesn't after reinstalling Office 2016?
Word may have encountered a specific registry corruption or an add-in conflict during the reinstallation that didn't affect Excel. Starting Word in Safe Mode (holding Ctrl while opening) can help bypass add-in issues.
Do I need to enter my product key every time I reinstall Office 2016?
No. Office 2016 licenses are usually digitally linked to your Microsoft account upon first activation. You should sign in with that Microsoft account instead of re-entering the product key.
What if my Office Professional Plus 2016 product key is rejected?
Office Professional Plus is typically a volume license meant for corporate environments. If you purchased it from a third-party seller for personal use, Microsoft may have revoked the key for violating terms of service.
How can I quickly access my Word files if Microsoft Word won't open?
You can upload your documents to Microsoft OneDrive to view them in Word for the Web, or install a free alternative like WPS Office to open and edit your local files immediately.
