Looking to install latest ver. of LR6

Hi @Howard5252,

Just to clarify terms a bit, Adobe owns the software.  You have a limited license to use it for as long as Adobe can make it available. LR6 came out in 2012.  It's discontinued and no longer supported so you're living on borrowed time.  

When you're ready to upgrade, the Photography Plan is a deeply discounted bundle.  And it's updated regularly to keep it current with modern OSs and cameras. For USD $10/month for 12 months, you get these great products & services:
-- Photoshop CC and Photoshop on iPad
-- Lightroom on desktop, mobile and the web
-- Lightroom Classic
-- Portfolio website + hosting
-- Spark with premium features
-- Bridge
-- 20 GB cloud storage (upgradable to 1 TB).

IF/When you do have a download, be sure to copy it to AT LEAST one external device
-since Adobe does sometimes remove old versions from the server
-a usb flash drive or hard drive, or write to a DVD
-plus a text file containing your serial number
