Litghtroom 5.7 to actual version (7.4.1) not supported

So is this the new Lightroom 5.something which is likely 2-3 years old, or the Lightroom 5.something from over a decade ago? Do you pay by subscription for this Lightroom 5.something, or is it a single time purchase?

I am guessing, please confirm, that you have the very old Lightroom 5.7 (let's say more than a decade old, single purchase not subscription) and you want to upgrade it to the current Lightroom Classic version 13.4 (which is the successor to the very old Lightroom 5.7), and not the cloud-centric Lightroom 7.4.1 (which is not the successor to Lightroom 5.7). But maybe you really do want to use the cloud-centric Lightroom 7.4.1.

Yes, it is confusing.
