Solution 1Recommended

Run a Full Online Repair via Control Panel

Using the built-in Windows Control Panel to perform a full online repair is the most effective way to resolve persistent Office application crashes and repair loops.

When the built-in 'Repair Now' button fails to work, it indicates that the Office installation files are deeply corrupted. An Online Repair completely replaces these corrupted files by downloading fresh ones directly from Microsoft servers.

1
Open Control Panel

Click the Windows Start menu, type 'Control Panel' in the search bar, and press Enter to open it.

2
Navigate to Programs

Under the 'Programs' section, click on 'Uninstall a program' to view the full list of software installed on your computer.

3
Locate Microsoft 365 Apps

Scroll through the application list, find 'Microsoft 365 Apps' (or your specific Office version like Office 2021), right-click it, and choose 'Change'.

4
Select Online Repair

In the repair dialog box that appears, select 'Online Repair' (or the full repair option) instead of Quick Repair, and click 'Repair' to begin downloading fresh installation files.

5
Restart your Computer

Once the online repair process completes successfully, restart your computer to apply all system changes before attempting to open Word or PowerPoint again.

Quick Repair vs. Online Repair: While Quick Repair is faster and runs completely offline, it often fails to fix complex startup and crashing issues. Online Repair performs a comprehensive reinstallation of the applications, which is why it requires an active internet connection.

Frequently Asked Questions

Why does Microsoft Office keep asking me to repair it?

This usually happens due to corrupted program files, conflicting third-party add-ins, or incomplete Windows updates interfering with the software registry. When the 'Repair Now' button fails to apply a fix, performing a full Online Repair from the Control Panel is typically necessary.

Will performing an Online Repair delete my Word and PowerPoint files?

No, performing an Online Repair will only reinstall and fix the Microsoft Office application files. Your personal documents, presentations, saved templates, and user data will remain completely intact on your hard drive.

What should I do if the Online Repair doesn't work?

If the Online Repair fails to resolve the crash loop, you may need to completely uninstall Microsoft Office using the official Microsoft Support and Recovery Assistant (SaRA) tool to clear out corrupted registry keys, and then reinstall the software suite from your Microsoft account.

Can opening a specific corrupted document cause the repair prompt?

Yes. If the application only crashes and shows the repair prompt when opening one specific file, the document itself might be corrupted. Try opening Word or PowerPoint first, then navigating to File > Open > Browse, selecting the file, and choosing 'Open and Repair' from the drop-down menu on the Open button.
