Duh ... (Sorry!)
That's what I tried to do. That's what the support tech said he did by remote access. That's what the link on the Adobe page said it was (LR6). That's what the downloaded file was listed as.
But what downloaded and actually installed was LR CC (2015).
How do I get the CORRECT version downloaded ... or failing that, get a refund?

You have downloaded the right program, but it is being authorised by your Adobe account, which doesn't have a subscription.
To correct this you need to sign out and restart it with the registration code. See How to convert a Lightroom CC trial to Lightroom 6
Out Frickin' Standing!
This was the answer I was looking for ... Mission accomplished. I now have a stand alone copy (updated to 6.14) on my "offline backup computer." (And it doesn't even ask me to sign in ... Perfect! Exactly what I needed.)
Thank you John ... I doubt I would have found this particular information without your help.
Thank you for the phone number. It turns out I don't need to ask for a refund. John has provided me with a PERFECT answer. (See his reply.)
