P: Error at loading of ippCV library

Bonjour Jeffrey,

Nous attendons avec impatience le correctif d'ADOBE ou bien une solution explicative détaillée pour résoudre ce problème.

Merci

I will need to ask the engineers who know more about it.

So Jeffrey, does Adobe have any response to the fix posted above by shad0w?

Worked for me.

Photoshop 2021 (v22.x) requires a CPU that supports SSE 4.2 or later.

To determine if your CPU meets this SSE version support requirement, see Photoshop's Help > System Info dialog and look in or near the 4th line.

Adobe Photoshop Version: 22.0.0 20200921.m.1053 2020/09/21: 0fb66349f4  x64
Number of Launches: 6
Operating System: Mac OS 10.15.5
ystem architecture: Intel CPU Family:6, Model:14, Stepping:3 with MMX, SSE Integer, SSE FP, SSE2, SSE3,SSE4.1, SSE4.2, AVX, AVX2, HyperThreading
 

Sure, feel free to share 😉

Real bug here is to require support for SSE4.2.
For what? Used libraries (IPP and OpenCV) allows to run on CPUs without SSE4.2 just fine without any additional effort from developers and without affecting performance for those who do have SSE 4.2.
How come AMD Phenom II X4 965 Black Edition (4 cores @ 3.4 GHZ) or AMD Phenom II X6 1075T (6 core @ 3.0 GHz) is not sufficient to run PS 2021, while Intel Core i3-2310M (2 core @ 2.1GHz) is considered enough?
It's a very unwise decision to say the least, and it's a shame...

You wrote "It would be right for Adobe to back down and review this very dubious and counterproductive choice for marketing. Otherwise it should reimburse its customers who have computers that are not recent but still do their job! [Google translate from Italian]"

Federico gessi: Just how does your comment advance a solution? Read what others have provided

Thank you very much.  I looked for this missing file but found it nowhere.  I will try this, though I already ordered an upgraded CPU for one of my installations.

Why is this not a no brainer that Adobe should provide this file or tell us that we need to do the above?

I tried this and it worked on my Win10-64 pro AMD Phenom II 1100T CPU.

I'm going to cross post your instruction to another forum if you don't mind.

If you got this error:
"
    Error at loading of ippCV library
 
    Your application is dynamically linked with Intel(R) IPP libraries version 2020.0.1.
    No DLL from the list below is found an the system search path:
     ippcvm7.dll (the most suitable for your CPU)
    Please provide a path to at least one of them.
"
Here is the fix.

Despite what Adobe is saying officially, Photoshop 2021 does NOT require support of SSE4.2 to run.
The real problem is that:
- IPP libraries optimized for SSE3 are missing from distribution (they are available from Intel)
- OpenCV library was build with SSE4.2 requirement
To fix this download this pack of libs from any source below (it's the same):
https://www113.zippyshare.com/v/cqtznzt2/file.html
https://www.sendspace.com/file/vh0wjm
Unpack archive and copy libs to Photoshop 2021 installation directory (overwrite opencv_world440.dll when requested).

This fixes the problem an PS runs just fine.
But disclaimer as usual - all this at your own risk.

Please note that this is not a hack or something like this - this is official libraries from official sources.
Intel IPP libraries was taken from Intel Parallels Studio XE 2020.1.0 and contains valid signature from Intel.
OpenCV library was taken from official release of OpenCV 4.4.0 on GitHUB (https://github.com/opencv/opencv, build by VC15).

Photoshop 2021 (v22.x) nécessite un processeur prenant en charge SSE 4.2 ou version ultérieure.

Pour déterminer si votre processeur répond à cette exigence de prise en charge de la version SSE, consultez la boîte de dialogue Aide> Informations système de Photoshop et regardez dans ou près de la 4ème ligne.
