How to Fix Office 365 Applications Crashing on Windows 10
Question details
Users need to resolve an issue where Microsoft 365 applications unexpectedly crash and display an error message stating that the program must close, especially when the basic quick repair option fails.
- Product
- Microsoft Office 365
- Device & OS
- Windows 10
- Scenario
- Launching or working within Microsoft 365 applications.
- Observed behavior
- The application displays an error stating it has encountered a problem and must close, and the built-in quick repair option does not resolve the crash.
Save any recovered documents if prompted upon reopening, and ensure you have your Microsoft account credentials handy before initiating a full online repair or reinstallation.
Run an Online Repair for Microsoft Office
Use the comprehensive Online Repair tool via the Windows Control Panel to fix deep-seated issues that the standard quick repair cannot resolve.
Click the Start menu, type 'Control Panel', and press Enter. Navigate to Programs, then select Programs and Features.
Scroll through the list of installed applications, right-click your Microsoft Office 365 installation, and select Change.
When the repair dialogue appears, choose Online Repair instead of Quick Repair, then click Repair to initiate the process. This requires an active internet connection.
Install Windows Updates and Perform a Clean Boot
Ensure your system is up to date and rule out third-party software interference by running Windows in a clean boot state.
Completely Uninstall and Reinstall Office
If all repair methods fail, a clean installation of Microsoft 365 will replace all potentially corrupted application files.
Switch to WPS Office for a Stable and Lightweight Experience
If Microsoft Office 365 continues to crash or requires tedious repairs, consider switching to WPS Office. It provides a highly compatible, fast, and free alternative that installs quickly and runs smoothly on Windows 10 without heavy system resource consumption.
- 1. Download the Installer: Visit the official WPS Office website and download the free installation package for Windows.
- 2. Install the Suite: Run the setup file and follow the simple on-screen instructions. The lightweight installer takes only minutes to complete.
- 3. Open and Edit Your Files: Launch WPS Office and directly open your existing Word, Excel, or PowerPoint files without worrying about formatting loss.
Frequently Asked Questions
Why does Microsoft Word suddenly say it encountered a problem and needs to close?
This usually happens due to corrupted application files, incompatible third-party add-ins, or pending Windows system updates that conflict with Office 365 components.
What is the difference between Quick Repair and Online Repair in Office?
Quick Repair fixes minor issues offline by replacing corrupted files quickly. Online Repair is a more thorough process that requires an internet connection; it uninstalls and cleanly downloads the Office suite components again to fix severe issues.
Will reinstalling Office 365 delete my personal documents?
No, uninstalling or repairing Microsoft Office 365 will only remove the application files. Your personal Word documents, Excel spreadsheets, and PowerPoint presentations stored on your computer or OneDrive will remain entirely untouched.
How do I start Word in Safe Mode to check for add-in issues?
Press the Windows key + R, type 'winword /safe', and press Enter. If Word opens normally without crashing, an installed add-in is likely causing the problem and should be manually disabled in the settings.
