A family of Microsoft word processing software products for creating web, email, and print documents.
All Office product keys are version (2016, 2019, 365 etc ) and bundle (Home, Home and Student, Professional etc) specific. A 2016 key can only activate 2016 etc.
If you have 2 unactivated copies of Office, the activation system WILL get confused if you try to activate the more recently installed one.
- Go to Control Panel > Programs and Features.
- Look through the list of installed programs
- If you find 2 versions/bundles uninstall the unwanted one
- Repair the required one
