LR notified me when I started it up today that there is an update available. I clicked on the link -- and it took me to a general LR page. Options were Trial or Buy now, etc. Nothing indicating update for existing software. What do I do? Download the full package? My details are:
Lightroom version: 5.7 
License type: Perpetual
Operating system: Windows 7 Home Premium Edition
Version: 6.1 
Somehow, I found an Updates page awhile ago and installed that, but I can't find it again. This is NOT very friendly....
BTW, I do NOT want to join Creative Cloud -- software only please.
The "update" that is being referred to is actually an "upgrade", which means you have to pay for it (or try the 30-day free trial and then pay for it).
You can upgrade to Lightroom 6 (no Creative Cloud) at Products (scroll down to Lightroom 6)
Right. Well, that explains it!
