Solution 1Recommended

Clean Reinstall Using Microsoft Support and Recovery Assistant

Completely remove corrupted Microsoft 365 files and perform a fresh installation to permanently resolve both the startup and repair errors.

These specific error codes indicate deep corruption in the Office installation files or Windows registry that the standard Windows uninstaller cannot resolve. Utilizing the dedicated Microsoft Support and Recovery Assistant (SaRA) ensures all remnants are cleared.

1
Download the Uninstall Tool

Visit the official Microsoft download link (aka.ms/SaRA-officeUninstallFromPC) to get the Office uninstall tool executable.

2
Run the Uninstaller

Launch the downloaded file and follow the on-screen prompts to completely wipe all previous Microsoft 365 installations from your system.

3
Restart Your Computer

Click the Start menu and manually select 'Restart'. Do not simply shut down the PC, as Windows Fast Startup might preserve the corrupted system state.

4
Reinstall Microsoft 365

Navigate to account.microsoft.com/services in your web browser, sign in with your Microsoft account, and download the latest Microsoft 365 installer to reinstall the suite.

Frequently Asked Questions

Why do I get error code 0x3-0x0 when launching Office apps on Windows 11?

This error typically occurs when Microsoft 365 background services or essential core files become corrupted, preventing the applications from initializing properly on your operating system.

What causes error 30175-13 during a Microsoft 365 repair?

Error 30175-13 appears when the built-in Microsoft 365 repair tool encounters heavily damaged or missing installation files. Because the foundational files the tool needs to run the repair are broken, a complete uninstallation is required.

Will using the Microsoft uninstall tool delete my personal documents?

No, the Microsoft Support and Recovery Assistant only removes the software application files and registry keys. Your personal Word, Excel, and PowerPoint documents saved on your hard drive or OneDrive will remain completely safe and untouched.
