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

https://helpx.adobe.com/photoshop/kb/known-issues.html#ErroratloadingofippCVlibrary

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.

  1. Adobe Photoshop Version: 22.0.0 20200921.m.1053 2020/09/21: 0fb66349f4  x64
  2. Number of Launches: 6
  3. Operating System: Mac OS 10.15.5
  4. ystem architecture: Intel CPU Family:6, Model:14, S

Thanks FSt0p, 

Your solution worked for me.  This avoided having to buy a new CPU/motherboard.  

I'm going to paste your solution again below in hopes that more people will see it.

----------------------------------

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).
