P: Allow CPUs without AVX2 to install Adobe Products

@ThomasH_on_the_web 

To summarize:  So far Adobe did not made any effort to chime in, and to explain anything.  Moderation of messages is always somewhat arbitrary, as arbitrary as people can be with their opinions. The merit of the problem here is:

1. Adobe simply assumes that a vast majority of users have more modern computers, do not maintain existing systems over prolonged periods of time. Consequently to them this here is a "marginal issue."
2. They do not care how to discover which processor has AVX2. They assume "every current one has." 
3. Admitting to a mistake and/or even a reversal is probably impossible in the current culture at Adobe. Might cost position, influence or even the job. 
4. List of processors, alone from Intel and AMD, is excessive. It is difficult to make a proper decision based on the scarce specs of each of the hundreds of processors. 
   
   

So realistically, aside of voicing the awareness for future cases, we all have invest in new hardware, unexpectedly. I am perusing regularly offerings from all major manufacturers, because my wife has the Z50-II, and we need the new Lightroom for our trip.  Someone mentioned here a whopping $3000 expense for his now obsolete system.  I hope that a new motherboard could solve this dire situation. Since I was not aware of AVX, my newest system with XEON has AVX2 only by coincidence.

Some decade age we encountered a rapid decline of HP and Dell hardware, caused by their focusing on games and overclocking. Since I focus on durability, I took XEON systems designed for 24/7 operations. This computer is really old: It is a T1600 Dell in my 2nd studio, also a XEON, but it does not has AVX2 because of its age: It went through Windows Xp-Windows 7-Windows 10 updates without any issue, has of course SSD now!  Now that's the end: The tower does not has TPM2, required by W11.

If I install LRC versions newer than 13.5.1 the Slide Show functionality is crippled and will not play. When I open the Slide Show panel it throws up the error about not being able find the Dynamic Link Server. CC tells me LRC 14.0 and 14.01 are compatible with my computer and that 14.3.1 is not.  Even so, as mentioned earlier, the Slide Show will not work with any 14+ version. My system is 10 years old now with an Intel i7-4930 processor. It may not even have AVX1 support. I don't know for sure. 

Finallly you asked about my comment "Anything newer than 13.5.1 will cause the Slide Show to stop working with an error message complaining about the dynamic link server not being found." Is that confirmation that you never had the latest version installed with an AVX processor (v14.01)? I'm not quite sure what yor asking other than to say I did install the new versions (14.0 and 114.01). When installed the Slide Show problem I describe occurs. When I revent to 13.5.1 Slide Show functions normally.

In any event it looks like going forward with Adobe will require new hardware. I'm stuck where I am for the time being.

I thought the small updates to the latest possible version with AVX would allow compatibility with new cameras. Then I was wrong, and this is a good indication that this is a worse problem than I'd already described.
Of course, the moderation is authoritarian, coming from the person listed as an Adobe employee. There was no dialogue possible: he told me, not by email, but directly on the forum, that after the third warning he would close my account. But what he did was close the thread, and I couldn't reply that I found it unfair to reprimand me without explaining why or being able to rationally defend my point. Since I had nowhere to respond, I opened a new thread, and he closed it. I complained via direct message, not a new thread, and they closed my account and deleted all my posts except this one, which was originally on the LRC forum and relocated here.
Interesting what you're suggesting about "Changing fate of Adobe by Touring Price category code." It would be good to elaborate a little more.
Greetings,

P.S. I spent US$3000 in 2012 on my computer and it's still very good, except for Adobe/Intel/AMD who want me to spend more.

@JLCKJC2015 
The slideshow and everything works perfectly on my computer with an AVX processor and LRC version 14.0.1.
To complement your information: you say you upgraded because the CCD didn't detect an incompatibility between your computer and the new version (at that moment), and after doing so, you had problems. Which upgrade version are you referring to? 14.01 or 14.1? Because, as we've said, 14.01 still allows processors with AVX, but 14.1 already requires AVX2. And finally, what processor do you have?
You say:
"Anything newer than 13.5.1 will cause the Slide Show to stop working with an error message complaining about the dynamic link server not being found." Is that confirmation that you never had the latest version installed with an AVX processor (v14.01)?
Cheers,

@ThomasH_on_the_web Very tongue in cheek! I still don't see why the newer versions require AVX2. I lucked out when I replaced my January 2006 system in November of 2018. The old system didn't even have AVX, and the newer cpu had both AVX and AVX2. I have another, newer machine (2020-2022) that missed the AVX512 bandwagon, so Adobe will probably force me to replace it in a year or two. You don't want to know how much I spent on it. I don't even want to know. I don't make a whole lot, and I saved for over a decade to build both newer machines. I don't know what I'll do next time the AVX and other requirements change. Sell my organs?

They deleted also one of my recent musings: A satire really. I wrote a message titled similar to "Changing fate of Adobe by Touring Price category code". The "top-secret" Touring Price category code is: 

boolean avx2=check_avx2();
if (avx2) do_new_stuff();
else do_old_stuff();

Someone got upset, and they 1st relocated the message (I received email about that from a "moderator") and than this message has vanished completely.  But aside of the sarcasm, the content has had a genuine merit. This is how we do it all the time. Backward compatibility in Database business is paramount. We have a subscription, and in order to use a new camera (Z50 II, I gave it to my wife) I needed to have a newest version of Lightroom. But no, I need to spend one more thousand on a new computer.

I'm curious, is your Slide Show panel fully functional with the 14.0+ releases?

I just tried again. Anything newer than 13.5.1 will cause the Slide Show to stop working with an error message complaining about the dynamic link server not being found.
