Sorry this is so confusing.. I agree that it is...
Flare 2016 r2 came *between* Flare 12 and Flare 2017. It was released sometime last fall, I forget exactly when. If MadCap had continued with their longstanding numbering scheme, Flare 2016 r2 would have been called "Flare 13" (and in fact was installed into a "MadCap Flare 13" folder). Just as with all prior "major" releases, it did not overwrite prior releases.
Now along has come Flare 2017 this week. It's really just "Flare 13.x". Given its release, the download link to the latest version of Flare will be 2017, so no "r2" in sight.
So, Marie Claire's original question was, will Flare 2017 overwrite Flare 12? No. They are different releases.
But if one had already installed Flare 2016 r2, will Flare 2017 overwrite it? Yes. They are both "Flare 13". This isn't any different from a "dot" release of Flare 12 overwriting the original release of Flare 12.

I hope this info helps.
(Personally, yes, I'm using Flare 2017. I've got a maintenance contract, so pay for my updates that way. I started immediately enjoying several new UI enhancements. Plus, I'm quite keen on the new "clean XHTML" target.)
