How to Repair Office 2013 When Word, Excel, and Outlook Won't Open
Question details
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.

- 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.
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.
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.
Press the Windows key, type 'Control Panel' into the search bar, and press Enter to launch it.
Click on 'Programs' and then select 'Programs and Features' to view a list of all software installed on your computer.
Scroll through the application list, find 'Microsoft Office 2013' (or your specific Office 2013 edition), and click to select it.
Click the 'Change' button located at the top of the program list window. If prompted by User Account Control, click 'Yes'.
In the dialog box that appears, select 'Online Repair' (not Quick Repair) and click the 'Repair' button. Once the process completes, restart your computer.

Run the Windows System File Checker (SFC)
If repairing Office directly doesn't work, use the System File Checker tool to scan for and fix corrupted Windows system files that might be preventing applications from launching.
Switch to WPS Office When Microsoft Office Fails
If Microsoft Office 2013 continues to experience application errors and won't open, WPS Office is a perfect, lightweight alternative. It is free to use, highly compatible with your existing documents, and helps you avoid the frustration of constant software repairs.
- 1. Download WPS Office: Visit the official WPS website and download the free installation package for Windows.
- 2. Install the Application: Run the downloaded installer. The lightweight package sets up safely in just a few minutes.
- 3. Open Your Office Files: Right-click your existing Word, Excel, or PowerPoint files and select 'Open with WPS Office' to continue your work seamlessly.

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.
