Perform an Online Repair for Microsoft Office

Use the built-in Windows Settings to run an Online Repair, which performs a thorough reinstallation of Office components to fix persistent crashing issues.

While a standard Quick Repair attempts to fix localized file issues, an Online Repair is much more comprehensive. It connects to Microsoft's servers to download and replace any missing or heavily corrupted Office files that are causing Word and Excel to close unexpectedly.

1
Open Windows Settings

Click on the Start menu in the bottom left corner of your screen and select the 'Settings' gear icon.

2
Navigate to Installed Apps

Click on 'Apps' from the Settings menu, and then select 'Apps & features' or 'Installed apps' depending on your specific version of Windows.

3
Modify Microsoft Office

Scroll through the list of installed programs to locate your Microsoft Office installation. Click on it (or click the three dots next to it) and select 'Modify'.

4
Select Online Repair

A window will prompt you to choose how you would like to repair your Office programs. Select 'Online Repair' and then click the 'Repair' button to initiate the process.

Restart Your Computer

Once the Online Repair has finished downloading and installing the necessary components, restart your computer to apply all changes and test Word and Excel.

Frequently Asked Questions

What is the difference between Quick Repair and Online Repair in Microsoft Office?

Quick Repair runs faster and operates entirely offline to fix minor registry or corrupted file issues. Online Repair is much more thorough; it completely uninstalls and then reinstalls the Office components by downloading clean versions from the internet.

Will I need my product key again after running an Online Repair?

In most modern versions of Microsoft Office and Microsoft 365, your license is tied to your Microsoft account, so you won't need a product key. You may just be prompted to sign back into your Microsoft account when you launch Word or Excel for the first time after the repair.

How long does an Online Repair typically take?

The duration of an Online Repair depends heavily on your internet connection speed and computer hardware. Generally, it takes anywhere from 10 to 30 minutes to complete the full reinstallation.
