Incidentally Office 2007 support ended nearly 5 years ago so has not received fixes or security updates in that time. LibreOffice is 'alive and well' and receives fixes and security updates. It gets good ratings by those who test these things and you may want to consider it as your main office suite now instead of MS Office? They can run alongside each other. They do not conflict so no need to uninstall MS Office 2007 unless you want to.

I have LibreOffice installed as well as my MS Office 2019 since it has some features that MS Office doesn't. The ability to redact documents being one.

Just a thought.
