HI! How can I upgrade my Lightroom 5.7 to 6?

You can purchase Lightroom 6 as a part of the creative cloud photography package, part of creative cloud, as a stand alone product or as a product upgrade. Please first verify that your system meets the system requirements .

If you purchased  a previous version of lightroom as a perpetual product rather than the creative cloud, you would need to purchase an upgrade to Lightroom 6. Udpdates are free for stand alone versions, but upgrades need to be purchased.

If you wish to purchase an upgrade to Lightroom 6 from an earlier version, please  see this link:  Products .  Scroll down to lightroom and click "buy". Click on the selectable text by " I want to: "and select "upgrade". Then select the version you are upgrading from in the pulldown.
