How do I uninstall/remove the Contribute add-in from MS Office Excel 2010?

I have uninstalled all Adobe products completely from my computer (only flash is still installed from Adobe). I also ran the Adobe Creative Cloud Cleaner Tool.

Still the Contribute add-in is present in excel. I have spoken with Adobe Support and they couldn't help me. They asked me to post on the Adobe Forum, and I have, but with no solution.

I have also tried to locate the add-in through excel:
- File
- Alternatives/Options
- Add-ins
- Then choose one of the following for "Manage": "Excel-add-ins", "com-add-ins", "action", "XML-extensions", "deactivated elements".

The problem is that I cannot find the Contribute add-in anywhere. So how can I disable an add-in I cannot locate?

Am I looking the wrong place?
