In a note, there is a solution for Windows OS and MacOS.
You can discuss this issue on the official Adobe Community Forum:
One of the users, the owner of a licensed version of Photoshop, addressed a problem, after updating Photoshp, an error message began to appear about the lack of ippsvm7.dll in Photoshop.
Situation.
System: licensed OS Windows 10 Home, version 20H2
Photoshop Software: Officially Licensed
Problem: After updating Photoshop to version 2021, a message appears stating that the .dll file is missing:
ippcvm7.dll
Photoshop 2021 itself - does not open and displays the following error message:
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 a screenshot of the problem:
From this post, you can see a mention of the lack of ippcvm7.dll
Error code: r0x35c5ec66
Despite official statements from Adobe that Photoshop 2021 does not require SSE4.2 support to work correctly, the problem actually exists. The main reason for the issue in Photoshop 2021 with missing DLL ippcvm7.dll is that the IPP libraries optimized for SSE3 are not present in the Photoshop 2021 distribution (they are available from Intel), and the OpenCV library was built with the SSE4.2 requirement. To solve this problem, you need to download the library package.
Workaround (official proposal from Adobe).
This is not an official solution to the problem, since at the moment, Adobe officially denies the existence of this problem, claiming that this error occurs for those who do not meet the minimum requirements for working with Photoshop 2021. At the same time, on the official forum of those. Adobe support, official representatives recommend that those users who have an error with the missing DLL ippcvm7.dll, after updating Photoshop to version 2021, roll back the update to the previous version of Photoshop. If you wish, you can roll back the update according to these instructions and wait for a possible official decision from Adobe.
It is noteworthy that the problem is relevant for official and unlicensed versions of Photoshop.
Independently, you can familiarize yourself with one of the topics at the office. the Adobe forum on the issue of missing DLL ippcvm7.dll.
Recommendation.
Back up your system and check for driver updates for Intel. If there are Intel driver updates available for your device - install them and test Photoshop. Look for Intel drivers only on the official website.
Temporary working solution for Windows.
You can download ippcvm7.dll yourself and install the missing DLL files. For this, I placed an archive on my Google Drive with the necessary DLL files . Download ippcvm7.dl l for Windows using the link below.
My Google Drive:
Alternative download links (may not work):
The archive contains the following DLL files:
- ippccm7.dll
- ippcvm7.dll
- ippim7.dll
- ippsm7.dll
- ippvmm7.dll
- opencv_world440.dll
If the link doesn't work, please leave a message in the comment.
Advice.
Before adding files from the archive, I recommend that you create a system restore point and create a backup copy of the opencv_world440.dll file. To do this, you can simply right-click on the file, select "Rename" and add rezerv to the file name - for example. And for you, the file will already have the following name: rezerv-opencv_world440.dll. This will allow you to keep the original file, just in case. Since the archive contains this file, you need to add, replacing the original.
They need to be unpacked from the archive and added to the folder (installation directory) where you have Photoshop 2021 installed. When adding files, you will be prompted to overwrite the opencv_world440.dll file. Agree and overwrite the opencv_world440.dll DLL file.
The DLLs from the archive above are taken from the official OpenCV 4.4.0 release (build VC15) on GitHub and from the Intel IPP library, taken from Intel Parallels Studio XE 2020.1.0 and contain a valid Intel signature.

This method of solving the problem is not a hack or something like that. The solution uses official libraries from official sources.

Temporary working solution for macOS.

Alternative link (may not work):
The archive contains one file:
libopencv_world.4.4.0.dylib
If the link doesn't work, please leave a message in the comment.
Unzip the file and copy the resulting libopencv_world.4.4.0.dylib file to replace the same file in the Photoshop 2021 installation directory (\Applications\Adobe\Photoshop\2021\Adobe\Photoshop\2021.app\Contents\Frameworks\libopencv_world.4.4. 0.dylib).
The OpenCV library was taken from the official OpenCV 4.4.0 release on GitHub.

Adobe said and stressed that Photoshop 2021 (v22.x) requires a CPU that supports SSE 4.2 or newer.
On the forums, you can now see the outrage of users and accusations against Adobe that it (Adobe) is in collusion with Intel and forcibly forces users to update the hardware.
Conspiracy theories aside, one can only guess that in the near future, there may not be an official fix from Adobe. In any case, the official answer from Adobe on this situation remains unchanged for now:
«Use a previous version of Photoshop or upgrade the processor.»

Some owners of Windows OS, after adding dll-files, sometimes hangs / freezes / crashes of the Photoshop program. Try to check system files for integrity and
- Update Microsoft Visual C ++
- Install RuntimePack
- Check for Windows and driver updates.
Check your system for viruses. To do this, use the following utilities:

Starting from Adobe Photoshop version 22.3, you will receive an error when trying to add dll files. If you have an official version of Photoshop and earlier, you added dll files to fix the ippsvm7.dll error, then when you try to update to version 22.3, you will receive the following message:
Looks like Adobe implemented a lock to fix the dll. As of now, Photoshop 22.2 is still working with this fix. That being said, officials still state that Photoshop 2021 (v22.x) requires a CPU that supports SSE 4.2 or newer to run. There is no fix and it is unlikely to be (if it appears, I will add). There are two ways left:
- Use older versions of Photoshop (up to 22.2 and older) and manually add dll files.
- Upgrade your device with a CPU that supports SSE 4.2 or newer.
This problem with blocking .dll files from version 22.2 or higher is mentioned on the official Adobe community forum.
If you find a working solution for Photoshop 22.3, share it in the comments. Your information may be useful to other users.
It is important to note that the problem is relevant for owners of both the licensed version and the pirated version.

A user shared in a comment that on the pirated version of Photoshop, fixes with the addition of .ddl files only work up to version 22.1.1.138 of Photoshop. On newer versions, problems appear as on version 22.3 and higher.
I want to clarify right away that not all pirated assemblies are of high quality. Anyway, keep this in mind if you have a pirated version of Photoshop.
And thanks for sharing in the comments. Your information will certainly help other users who are trying to solve their problem.
Remember, using illegal software violates the law and is a serious threat to virus infection.
