Have you previously had any other versions of Office installed on the PC?
Exactly which version of Office 2016 is installed - standard / professional / other?
Have you tried un-installing and re-installing Office, or performing a repair on the installation?
Is this the "Office 365 ProPlus Click-to-Run" version of Office? We have seen issues where this install does not include the options needed by OfficeToPDF: https://officetopdf.codeplex.com/workitem/55

I have MS Office 2016 and .Net 4.7.02 installed. I tried several document conversions and the error is:
