Frequently Asked Questions

Why does Word keep saying it has encountered an error and must close?

This error is typically caused by corrupted Office installation files, problematic third-party add-ins, or conflicts with recent system updates that interfere with Word's core processes.

Will running a repair on Microsoft Office delete my personal files?

No. Running a Quick Repair or Online Repair only resets and fixes the application's program files. Your personal documents, spreadsheets, and other user data will remain completely untouched.

What should I do if both Quick and Online repairs fail?

If repairing does not fix the error, you may need to completely uninstall Microsoft Office using the official Microsoft Support and Recovery Assistant tool, then reinstall a fresh copy from your Microsoft account.
