How to Fix Microsoft Office Applications Crashing on Startup
Question details
The user needs to resolve an issue where Microsoft Office applications crash or close unexpectedly immediately upon launching.

- Product
- Microsoft Office
- Device & OS
- Windows
- Scenario
- Launching Microsoft Office applications such as Word, Excel, or PowerPoint.
- Observed behavior
- The Office application crashes or forcibly closes itself immediately during the startup screen.
Before proceeding, ensure your Windows operating system is fully updated, and temporarily disable any third-party antivirus software that might be falsely identifying Office processes as threats.
Open in Safe Mode and Disable Problematic Add-ins
Use Safe Mode to determine if third-party add-ins are causing the application to crash, and disable them permanently to restore normal functionality.
Safe Mode starts Office applications without loading any add-ins or custom extensions. If the application opens successfully in Safe Mode, it indicates that a recently installed or outdated add-in is the root cause of the crash.
Press the Windows key + R on your keyboard simultaneously to open the Run dialog box.
Type 'winword /safe' for Microsoft Word or 'excel /safe' for Microsoft Excel, and press Enter to launch the application in Safe Mode.
Once the application opens, click on File in the top-left corner, select Options, and then click on Add-ins from the left sidebar.
At the bottom of the window, select 'COM Add-ins' from the Manage dropdown menu and click Go. Uncheck all the boxes in the list to disable them, click OK, and restart the application normally to test.

Frequently Asked Questions
Will repairing Microsoft Office delete my personal files or documents?
No, running a Quick Repair or Online Repair from the Control Panel only replaces or fixes corrupted installation files within the software suite. Your personal documents, spreadsheets, and system settings remain completely unaffected.
Why do my Office apps work perfectly in Safe Mode but not normally?
Safe Mode loads the application in a basic state without any add-ins, third-party extensions, or custom toolbar settings. If the software works in Safe Mode, it strongly indicates that a conflicting or outdated third-party add-in is responsible for the startup crashes.
How do I know which specific add-in is causing Microsoft Office to crash?
You can identify the problematic add-in by using a process of elimination. Open the app in Safe Mode, disable all add-ins, and then re-enable them one at a time. Restart the application normally after enabling each add-in until the crash occurs again, revealing the culprit.
