After Activation: Lightroom now states Lightroom 6.14 instead of Lightroom CC 2015 (seems to be the identical product with only differences in licenses).After that, the auto-update will magically lead to a functioning LR Adobe Login and Product Activation if you start the Lightroom application itself.To solve the above problem, just open the installed program “Adobe Application Manager” – this will lead to an auto-update from the Adobe Application Manager over the internet.After Lightroom 6 si installed (which is in fact Lightroom CC 2015 if you open and check the freshly installed version), DO NOT open Lightroom because this will only lead to the “Can’t connect” problem (searching for the offline activation feature which Adobe provides requires a Response Code for the installer which is not available anywhere).Just ignore the error message for now and install anyway by pressing the “ask later” button.But after you provided all that information, you will get an error message saying: “Can’t connect to the Internet, check Internet settings” (or something similar). The installer wants you to login with your Adobe credentials and provide your Lightroom 6 Serial Number.If you install the last stand-alone version of Adobe Lightroom version 6.14 on a newly installed Mojave macOS you will encounter a new problem ( see this post from 2020) – here is how to solve it:
