SSE 4.2 issue on AMD cpu

Why has Adobe sold me a product which does not work due to its new 'requirements' for an Intel dll on my AMD based system?

"Intel® or AMD processor with 64-bit support; 2 GHz or faster processor with SSE 4.2 or later". My cpu is 64bit, runs Windows 10 with 6 cores @3.2ghz and is a good deal faster than a core i3 which is supported!

What does SSE 4.2 do within Photoshop and is there a better workaround than downgrading to an earlier version of Photoshop?

If I could get LR Classic and the 1Tb storage I'd be happy, but only the online version of LR is available in that plan. Any chance ideas please?

SSE isn't a DLL. It's a feature of the processor (hardware). AMD and Intel developed and competed to add extra features to processors, to make apps like Photoshop work faster, so it's no surprise Photoshop now needs it. Both AMD and Intel have been selling processors with SSE 4.2 since 2007. What is your specific CPU?

Thanks for taking the time to reply. It's a AMD Phenom II x6 1090T CPU, on an AM 3 socket.

Six cores, six threads @3500mhz.

Windows 10 build 19042

Ok, here's what I can figure out. Your CPU was at the battle front in the war between AMD and Intel, each of whom was trying to sell more CPUs because of different SSE enhancements. Although Phenom II was launched in 2008, it didn't have SSE 4.2. It stopped with SSE 3, and added SSE 4a. SSE 4a was AMD's attempt to get the high ground, but that was the point they lost the war; Intel never copied SSE4a, but AMD copied SSE 4.2. So, unfortunately, your 13 year old CPU design backed the wrong side. It's taken Adobe at least 10 years to back SSE 4.2, but that's where we are today. (I hope this is technically correct).
