Re: Purchased Access 2016 on Ebay
The link leads to an AccessRetail.img file. If what you purchased was a license key, you can still go to Microsoft's site to download the installer, and that's what I'd do anyway. bit.ly is a competitor to tinyurl and other "URL shortener" services.
The Access page is: https://products.office.com/en-us/access
I would presume the "Try Now" button would download the trial version which could be enabled by supplying a license key.
Do not be surprised if the key you received will not activate via the internet. You may have to use phone activation, but even that's a misnomer in a way these days. You're asked a couple of questions by a "bot" along with your mobile number (if you have one) and the confirmation code, which is ungodly long, which will allow you to complete activation is texted to you.

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