Hi,
You can choose the 32-bit version or 64-bit version of Office to install.
How did you install Office 2016?
If you use Office Deployment Tool to install Office 2016, you can change OfficeClientEdition="32" or OfficeClientEdition="64"
to confirm if you need to install 32-bit or 64-bit version Office.
