Fix Publisher and Excel Crashing After Office Repair Prompt
Question details
The user experiences sudden application crashes when attempting to use the built-in repair option after receiving an error prompt in Microsoft Publisher and Excel.

- Product
- Microsoft Publisher, Microsoft Excel
- Device & OS
- not provided
- Scenario
- Opening Microsoft Publisher or Excel triggers an error message offering a repair option, but clicking the repair button causes the program to close immediately.
- Observed behavior
- Selecting the 'Repair' option on the in-app error prompt fails to initiate the repair process and instead forces the application to shut down.
Before modifying your system settings, restart your computer to clear temporary system glitches, and ensure you have your Microsoft account credentials ready in case a full reinstallation is required.
Repair Microsoft Office via Windows Settings
Bypass the in-app error prompt and use the built-in Windows application repair tool to safely fix corrupted Office files without triggering a crash.
When the in-app repair function crashes, it usually means the core application files are too corrupted to self-heal. Using the Windows Settings menu allows the operating system to repair the suite externally.
Right-click the Start menu button and select 'Settings', then navigate to the 'Apps' or 'Apps & features' section.
Scroll through the list of installed applications until you find your version of Microsoft Office or Microsoft 365, then click on it and select 'Modify'.
In the pop-up window, choose 'Online Repair' (which is more comprehensive than Quick Repair) and click the 'Repair' button. Follow the on-screen prompts to complete the process.

Uninstall and Reinstall Microsoft Office
If the Windows repair tool is unable to resolve the critical error, performing a clean uninstallation and reinstallation of the Office suite is necessary.

Frequently Asked Questions
Why does clicking 'Repair' cause Excel and Publisher to close immediately?
The in-app repair function relies on core Office components to run. If these specific system files are heavily corrupted or missing, attempting to initiate the repair from within the application triggers a critical error, causing the program to shut down abruptly.
Will repairing Office through Windows Settings delete my Excel spreadsheets?
No. Running either a Quick Repair or an Online Repair from Windows Settings only replaces corrupted application files and registry keys. Your personal documents, templates, and spreadsheets will remain completely untouched.
What is the difference between Quick Repair and Online Repair?
Quick Repair attempts to fix minor issues quickly by replacing corrupted files locally without needing an internet connection. Online Repair is a much more thorough process that downloads and reinstalls the entire Office suite components, which requires an active internet connection but fixes complex issues more effectively.
