Adobe has said that Lightroom will be available as a stand-alone application "for the forseeable future". No one knows exactly what that means except Adobe, and I haven't seen a clarification.
CS6 will not be available as a standalone. It will exist only in the Creative Cloud.
For those of us on a fixed income. Adding monthly fees for software, IS NOT THE BEST ALTERNATIVE FOR US! "Read my comment again and note "on Social Security, and can't afford monthly Cloud fees"... So for me it's time to look for a stand alone when that day comes, that software is only available on the cloud. Someday you will grow up and have the same problem, NO MONEY!
I read that - but you seem to be labouring under the misconception that Adobe is a charity, not a business whose key aim is profit maximisation, not the warm glow that comes from helping people out.
To put it another way: Adobe's not trying to be "THE BEST ALTERNATIVE FOR [you]". It can and will do whatever it wants to do in order to enrure maximum return for its shareholders, and if there's "collateral damage" along the way, well that's the capitalist "American Way", isn't it?
To put it another way: your personal circumstances are not Adobe's problem, I'm afraid.
LR 5 is DEAD. No more updates of any kind, ever, never, dead product. Just like LR 1 through 4.
Actually if I read it correctly CS6 does allow users to install the newest version 9 of Adobe Camera Raw. This is the first PS version that allowed the installation of newer versions of ACR. It was originally shipped with version 7, then when PS cc came out with ACR 8 CS6 could use it and now that Adobe has updated/upgraded to ACR 9 CS6 can use that.
But I would suspect that is the end of the road.
And CS6 was still available to buy as of 2 months ago but has since been removed from the Adobe Products page. That is in the US of A.
