As an aside, given that "recycled licenses" for Office 2016 Pro Plus routinely cost about the same as the $11 paid for Access 2016, they're a better bargain and you get the entire office suite, including Access, in the bargain.
I have updated six computers now using recycled licenses purchased from eBay and have had no trouble except with one license key, which the seller promptly replaced with another when I let them know it didn't work.

Explanations exist; they have existed for all time; there is always a well-known solution to every human problem — neat, plausible, and wrong.
