The user needs a reliable method to repair Microsoft Office 2013 when core applications crash, display errors, or refuse to open using the standard in-app options.

How to Repair Office 2013 When Word, Outlook, and Excel Will Not Open
Product
Microsoft Office 2013
Device & OS
Windows
Scenario
Attempting to launch Word, Excel, or Outlook for work, but encountering application errors or immediate software closures.
Observed behavior
Office 2013 applications fail to open, immediately close upon launch, or display an application error message instead of functioning normally.
Before you start

Ensure you are logged into Windows with an administrator account and have an active internet connection, as the Online Repair tool requires downloading fresh installation files from Microsoft servers.

Solution 1Recommended

Perform an Online Repair via Windows Settings

Use the Windows Control Panel or Settings app to run a comprehensive Online Repair, which completely reinstalls Office files and is more effective than the in-app Repair Now prompt.

When Office applications are severely corrupted, they may fail to even launch the built-in repair sequence. Triggering the repair externally via Windows ensures the process runs without relying on the broken applications.

1
Open Windows Control Panel

Press the Windows key, type 'Control Panel' into the search bar, and press Enter to launch it.

2
Navigate to Installed Programs

Click on 'Programs' and then select 'Programs and Features' to view a list of all software installed on your computer.

3
Locate Office 2013

Scroll through the application list, find 'Microsoft Office 2013' (or your specific Office 2013 edition), and click to select it.

4
Trigger the Modifier

Click the 'Change' button located at the top of the program list window. If prompted by User Account Control, click 'Yes'.

5
Run Online Repair

In the dialog box that appears, select 'Online Repair' (not Quick Repair) and click the 'Repair' button. Once the process completes, restart your computer.

Internet Connection Required: Online Repair might take longer than a Quick Repair because it needs to download replacement Office files over your network.

Frequently Asked Questions

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

Quick Repair attempts to fix issues quickly by replacing missing or corrupted files using local data already on your hard drive. Online Repair is more thorough; it completely uninstalls and reinstalls the entire Office suite, which requires an active internet connection but fixes deeper registry and application errors.

Will running an Online Repair delete my Office files or emails?

No, repairing Microsoft Office only affects the software's application files. All of your personal documents, spreadsheets, presentations, and Outlook data files (.pst/.ost) will remain completely safe and untouched on your computer.

Why does the in-app 'Repair Now' button never work?

When an application displays an error message with a 'Repair Now' button, the core files running the application are often too unstable or corrupted to successfully execute the repair command. Initiating the repair externally from the Windows Control Panel bypasses the broken application entirely.

What should I do if SFC /scannow doesn't fix the issue?

If the System File Checker doesn't resolve the problem and Online Repair fails, you may need to completely remove Office 2013 using the official Microsoft Support and Recovery Assistant (SaRA) tool, and then perform a clean installation of the software.
