Before you start

Before attempting to repair the software, ensure you have your Microsoft 365 account credentials ready and close any other Microsoft Office applications running in the background.

Solution 1

Verify Account Subscription and Update Office

Use this method to ensure your Office software recognizes your newly purchased Microsoft 365 plan and is running the latest version.

Sometimes, the local installation of Word does not immediately sync with your updated Microsoft 365 license. Signing in with the correct account and forcing an update can resolve these temporary activation or crash errors.

1
Open Office Account Settings

Launch Microsoft Word or any other Office app like Excel. Click on 'File' in the top left corner, then select 'Account' from the bottom left menu.

2
Check User Information

Under 'User Information', confirm that the email address displayed exactly matches the Microsoft account used to purchase the Microsoft 365 subscription.

3
Force an Office Update

Click on 'Update Options' next to the Office Updates section, and select 'Update Now'. Wait for the process to complete and restart your computer.

Frequently Asked Questions

Why is Microsoft Word asking me to repair shortly after buying Microsoft 365?

This typically occurs if your local Office installation hasn't fully synchronized with your newly updated subscription status, or if the update process corrupted some background system files.

What is the difference between Quick Repair and Online Repair for Office?

Quick Repair scans and replaces corrupted files using local resources without needing an internet connection. Online Repair uninstalls the current suite and downloads fresh files from Microsoft servers, requiring a stable internet connection.

Will I lose my Word documents if I run an Online Repair?

No, repairing or reinstalling Microsoft Office only affects the application files. Your personal documents, files, and templates saved on your computer or in OneDrive will remain completely safe.

What should I do if Word freezes during the repair process?

If the repair process hangs for an extended period, restart your computer, ensure you are connected to the internet, temporarily disable third-party antivirus software, and attempt an Online Repair again from the Control Panel.
