A family of Microsoft word processing software products for creating web, email, and print documents.
Use an Online Repair of Office, then, if needed, reinstall Office. Since a basic repair already failed, follow these steps on Windows:
- Close all Office apps (Word, Excel, etc.).
- Open Settings (press the Windows key, select the gear icon, or use Start > Settings).
- Go to Apps (or System > Apps > Installed apps, depending on Windows version).
- Find the Microsoft 365 or Microsoft Office product in the list.
- Select it, then choose Modify (or Change), and when prompted choose:
- Online Repair > Repair (this is more thorough than Quick Repair and replaces corrupted files).
- Let the repair complete and then try Word again.
If Word still shows errors after Online Repair:
- Uninstall Office from Settings > Apps > Apps & features (or Installed apps).
- Restart the PC (a full restart, not just shutdown).
- Install Office again from the Microsoft account or original source.
If the error is about a specific document (Word opens, but one file is broken), use Word’s document repair:
- Open Word.
- Select File > Open.
- Browse to the document, click it once to select.
- Use the arrow on the Open button and choose Open and Repair to let Word try to fix that file.
