Lightroom 6.14 stopped working in Mac OS Sonoma

A major issue with installing Lr perpetual v6 on a MAC is the install script is 32 bit, this is not the case for v4, v5. And starting at MACOS Catalina, Apple prevents with no exception running 32bit.

A workaround was to revert the MACOS, install, then upgrade the MACOS

HOWEVER, that works for Intel CPU MACs, not m1, M2, M3. On the newer MACs, no way to install the old Lightroom perpetual.

As for licensing issues, and this is tricky, contact Adobe. Inform them the call is for licensing issue only, not tech support for issues with the software. Cross fingers that you got a nice customer support person. Issue being Adobe no longer supports v6 and as such provides no help (with a possible non official exception for licensing)

Yet LR4 still works, which indicates there should be a way to get 6.14 running again.

Not necessarily. Lightroom 4 did not require you to activate the license. The license number was verified during installation, and then never again. Lightroom 6 did have an activation, so that may be what is causing the crash right now.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
