1. Libre Office cannot open a document that is password protected for opening without the password. Something other than a password must be getting in the way. What happens if rather than double-clicking on it, you simply open from within Word?
2. You can get a free trial of Office 365 which is a little later version of Office 2016.
3. Office 2016 is not available directly from Microsoft. Some retailers still have it. Microsoft is selling Office 2019.
4. If purchasing newer office (2016, 2019,365), note which applications are included.
