Frequently Asked Questions

Why did my Office applications suddenly stop working?

This can happen due to interrupted Windows updates, corrupted installation files, conflicting third-party add-ins, or expired software licenses.

Will I lose my PowerPoint presentations if I repair Office?

No, running the Quick Repair or Online Repair tool only fixes the application system files. Your personal presentations and documents remain safe on your local drive.

How do I open my presentations if PowerPoint refuses to launch?

You can use a free alternative like WPS Office to open your .pptx files immediately, or upload the file to a cloud service like OneDrive to view and edit it in a web browser until the desktop app is repaired.

Where can I find the crash logs for Office applications?

You can find crash logs by opening the Windows Event Viewer. Navigate to Windows Logs > Application, and look for 'Error' entries related to PowerPoint.exe or WinWord.exe.
