Fix Word and Excel Crashing or Showing a Repair Prompt
Question details
Users experience immediate application crashes or a continuous "Repair Now" prompt when attempting to open Microsoft Word or Excel, and the built-in repair button fails to resolve the issue.

- Product
- Microsoft Word, Microsoft Excel
- Device & OS
- Windows
- Scenario
- Opening a document or launching the Word/Excel application
- Observed behavior
- The application closes immediately upon launch or displays a "Repair Now" prompt. If the user clicks Repair, the program may remain usable for a few minutes before crashing again.
Before proceeding with an Online Repair, save your work in all other open applications and close them, as the repair process may require a complete system restart to finish.
Run an Online Repair from Windows Settings
Bypassing the faulty in-app repair button and using the Windows Settings repair tool is the most effective way to fix corrupted Office installations.
When the core Microsoft Office installation files are damaged, the in-app "Repair Now" button often fails because it relies on the very components that are broken. Running an Online Repair from your system settings downloads fresh replacement files from Microsoft.
Click the Start menu and open Settings. Select "Apps", then choose "Installed apps" (or "Apps & features" on older Windows 10 versions).
Scroll through the list of installed programs or use the search bar to find "Microsoft 365" or "Microsoft Office".
Click the three dots (or left-click the app) and select "Modify". When prompted, choose "Online Repair" (not Quick Repair) and click "Repair" to begin the process.

Test in Safe Mode and Disable Add-ins
Faulty or outdated add-ins can cause Word and Excel to crash instantly upon launch. Safe mode helps identify if an add-in is the culprit.
Install Pending Windows and Office Updates
System and software updates frequently contain bug fixes for compatibility issues and crashing behaviors.
Switch to WPS Office for a Stable, Crash-Free Experience
If Microsoft Word and Excel continue to crash or get stuck in a frustrating repair loop, consider switching to WPS Office. It provides a lightweight, highly stable environment that is fully compatible with all your existing documents without the need for constant repairs.
- 1. Download WPS Office: Visit the official WPS website and download the free installation package for Windows.
- 2. Install the Software: Run the downloaded installer and follow the quick setup instructions to integrate WPS with your system.
- 3. Open Your MS Office Files: Double-click any existing Word or Excel file to open it seamlessly in WPS Office and resume your work without crashes.

Frequently Asked Questions
Why does the in-app 'Repair Now' button fail to fix the issue?
The in-app repair button relies on the core Microsoft Office components to function. When the underlying installation is heavily damaged, the program cannot execute its own repair sequence, which is why triggering an Online Repair directly from Windows Settings is the recommended solution.
Will running an Online Repair delete my Word documents or Excel spreadsheets?
No, repairing Microsoft Office only reinstalls and fixes the application files. Your personal documents, spreadsheets, and data stored on your hard drive or cloud storage will remain completely unaffected.
What should I do if the Windows Update screen is blank while Office is crashing?
A blank Windows Update screen with moving dots often indicates a stalled background process, sometimes related to an Office repair trying to run invisibly. Restarting your computer will usually clear this stalled process, allowing you to access Windows Update and properly run the Office Online Repair from Settings.
