This could happen if the installation process did not complete when you tried to install a new program or the uninstall process did not go through as expected. Or the previously installed Office program installation files may have got corrupted.

If you cannot uninstall Office, use the following tools.

3] Office Uninstall Support Tool

• Download the Microsoft Office Uninstall Tool from Microsoft.
• Run the o15-ctrremove.diagcab, and it will launch the uninstaller.
• Use it to altogether remove your Office installation.

4] Microsoft Support and Recovery Assistant

Microsoft Support and Recovery Assistant will help you uninstall Office programs and resolve Office 365 apps, Outlook, OneDrive, Windows, Dynamics 365 & other problems.

5] Microsoft Fix it

• Use Microsoft Fix to uninstall Office. But first, check if it applies to your Windows and Office installation version.
• You can also use this Troubleshooter from Microsoft that lets you uninstall the latest Office or Office 365 version from Windows entirely.

Do note that Microsoft no longer supports using the Windows Installer Cleanup utility.

6] RipOutOffice2007

If you are using Office 2007, you could try this utility called RipOutOffice2007. Create a system restore point first before using this software. RipOutOffice2007 is a 3rd party freeware tool to completely uninstall & remove Office 2007 from your PC when the standard uninstall process fails. But the comments show this tool does not work in Windows 7 properly.

What happens if I uninstall Microsoft Office?

The documents created by Microsoft Office, i.e., DOCX, PPTX, XLSX, will not open unless you can use an alternate app that supports it. It may also happen that some custom functions only supported by Microsoft Office apps will stop working. However, you can upload these files into OneDrive and still use them.

Do I need a product key to reinstall Office?

You don’t need a product key to reinstall Office unless you have bought a standalone version of Microsoft Office. The application will install, and then you can sign in using the Microsoft account connected to your Office purchase. Once you do that, your copy of Microsoft Office will activate itself. Since this is a subscription-based model, your Office application functionality will be reduced if that expires.
