VBA concern: support for macros or controls not installed when software was installed

Background: I want to use Zotero, a citation manager, on Word but it uses macros. 

I get an error message every time I open Word saying VBA wasn't installed at the time I downloaded Office. Image of the error message screen shotted below. 

I have tried a number of different things: 

• Macros are enabled in the trust centre 
• VBA are enabled in the trust centre 
• I have ran rapid and online repair on Office on the control panel 

I have attempted 'change' office on my control panel to access the 'expand/add features' with the hopes of getting VBA but this does not appear as an option for me. When I select 'change' in the Control Panel the follow pop up appears: 

My current impression is that I must download VBA to be able to use VBA. I appreciate that VBA is supposed to automatically download with Office but this does not seem to have happened in my case. 

Please advise on what I should do next. 

Thanks in advance.
