If you have Office 2016, you should be able to upgrade to the 64-bit version through Microsoft’s standard upgrade process if for some reason it hasn’t already been updated. If your version of Microsoft Office is older than Office 2016 v15.35, you’ll have to choose from a variety of costly or time consuming and complicated options.
