Solution 1Recommended

Restart Your Computer and Run Office Repair

The most effective way to resolve core application corruption is to restart your system and utilize the built-in Windows repair tool for Microsoft Office.

Restarting your computer clears temporary memory glitches that might be causing Word to fail. If the error persists after a reboot, running the official Microsoft Office Repair tool from your Windows settings can safely replace missing or corrupted application files without affecting your personal documents.

1
Restart your computer

Close all active windows, restart your computer, and try opening Microsoft Word again to see if the issue is resolved.

2
Access Apps and Features

If the error continues, right-click the Windows Start menu button and select 'Apps and Features' or 'Installed apps' from the menu.

3
Locate Microsoft Office

Scroll down the list of installed programs to find your Microsoft Office suite. Click the three vertical dots next to it (or select the app) and choose 'Modify'.

4
Run the Repair Tool

Select 'Quick Repair' and follow the on-screen instructions. If Quick Repair does not fix the issue, run the 'Online Repair' option for a more thorough fix.

5
Restart after repair

Once the repair process is fully complete, restart your computer one final time before launching Word.

Admin Privileges Required: You may be prompted by User Account Control (UAC) to allow the app to make changes to your device. Click 'Yes' to proceed with the repair.

Frequently Asked Questions

Will repairing Microsoft Office delete my Word documents?

No. Running the Quick Repair or Online Repair tool only replaces or fixes corrupted Microsoft Office application files. Your personal documents, spreadsheets, and files are completely safe and will not be deleted.

What is the difference between Quick Repair and Online Repair?

Quick Repair runs entirely offline, takes only a few minutes, and fixes the most common issues. Online Repair takes longer and requires an internet connection because it downloads fresh installation files from Microsoft's servers to perform a comprehensive fix.

Why does Microsoft Word suddenly say it encountered an error?

This error typically occurs due to corrupted application files, conflicts with outdated third-party add-ins, a glitch during a recent Windows or Office update, or insufficient system resources.

What should I do if the Office repair tool fails to fix the error?

If both Quick and Online repairs fail, you may need to completely uninstall Microsoft Office using the official Microsoft Support and Recovery Assistant (SaRA) tool, and then reinstall the suite from your Microsoft account.
