Run the Uninstaller

Restart Your Computer

Once the tool finishes removing all Office components, restart your computer to clear any residual background processes and apply the changes.

Frequently Asked Questions

What exactly causes Microsoft Office error 30015-11?

This error is typically caused by a corrupted Microsoft Office installation, damaged system registry keys, or conflicting background processes that prevent the built-in Online Repair tool from overwriting the damaged files.

Will using the Office Scrub tool delete my Excel and Word files?

No, the Support and Recovery Assistant only removes the Microsoft Office software applications and configuration files. Your personal documents, spreadsheets, and presentations saved locally or on OneDrive will remain entirely safe.

Can I just uninstall Office through the Windows Control Panel instead?

You can try uninstalling via the Control Panel first, but error 30015-11 usually indicates deep-rooted corruption. The standard Windows uninstaller often leaves behind corrupted residual files and registry keys, making the OffScrub tool a much more reliable solution.
