All microsoft tools not working

Use an Online Repair of Office, because the built‑in “Repair now” from the error dialog is often not sufficient.

1. Close all Office apps (Word, Excel, PowerPoint, Outlook, etc.).
2. In Windows 10/11, open Settings → Apps → Installed apps or Apps & features.
3. Find the Microsoft 365/Office product in the list, select it, and choose Modify.
4. When prompted how to repair, choose Online Repair (more thorough than Quick Repair), then select Repair and follow the prompts.
5. When the repair completes, restart the computer and try opening Word and the other Office apps again.

If Online Repair does not resolve the issue, completely uninstall Office from Settings → Apps, restart the PC (not just shut down), then reinstall Office from the associated Microsoft account.

As the AI bot said, Repair Now is often not helpful. Instead, restart your PC and then perform an Online Repair (note that a reinstall is usually required as the final step of such a repair).
