Run the Full Office Repair Tool from Windows Settings
Bypass the faulty error dialog and use the official Windows application manager to perform a comprehensive repair of your Microsoft Office installation.
The automated repair button inside the Excel error dialog often performs a superficial check that fails to resolve deep system conflicts. Launching the repair tool directly from Windows Settings ensures a thorough restoration of missing or corrupted files.
Right-click the Windows Start menu and select 'Apps and Features' or 'Installed Apps' depending on your Windows version.
Scroll through the list of installed applications until you find your version of Microsoft Office or Microsoft 365.
Click the three dots (or left-click the app) and select 'Modify'. When the Microsoft Office prompt appears, choose 'Online Repair' for the most comprehensive fix and follow the on-screen instructions.

Completely Uninstall and Reinstall Office

Frequently Asked Questions
Why does the Repair button in the Excel error dialog do nothing?
The built-in prompt often tries to run a quick background fix that fails if core application files or registry keys are severely corrupted or locked by another process. Using the full Online Repair tool from Windows Settings bypasses this limitation.
Will repairing Microsoft Office delete my Excel files?
No, running an Office repair or completely reinstalling the application will not delete your personal files, workbooks, or documents. However, custom application preferences or temporary configurations might be reset to their default states.
What is the difference between Quick Repair and Online Repair?
Quick Repair attempts to replace corrupted files quickly without needing an internet connection, using locally cached files. Online Repair completely reinstalls the Office applications by downloading fresh files directly from Microsoft servers, which takes longer but fixes more stubborn issues.
