P: Photoshop Beta & v26.1 on Windows - Launch Error: dxcore.dll

[ValeriiN]

Today after the update I encountered that my Photoshop won't open due to this error: “(Photoshop beta.exe) Failed to continue code execution because the system did not detect dxcore.dll. To fix this error, try reinstalling the application.”
---

I have reinstalled several times already, but it didn't help me in any way. I also searched for solutions, but found nothing useful 😞
Since I urgently need the program for work, I wanted to install at least the previous version, but from what I understand, it is not possible to do so
---

Does anyone know how to fix it or how to install the previous version?

Hi @ValeriiN do you have the same issue launching Ps release version?

It is possible to roll back to a previous Ps beta version:

I wanted to do a rollback to a previous version
But I only see the current version 26.1

Hi @ValeriiN let's log out and then back in to CCD, then restart your computer and let us know if you see the option.

Thanks,

[ValeriiN]

I took this action
But it didn't help, I still only see the latest version of Photoshop Beta.

[CShubert]

Thank you for the update @ValeriiN , again, can you launch Ps release version, what happens when you try that?

Try resetting Prefs for the Beta:
/Users/yourname/Library/Preferences/ Photoshop Beta Settings (Mac Ventura)
/Users/yourname/Library/Preferences/Adobe\ Photoshop\ \(Beta\)\ Settings (Mac)


C:\Users\user name\AppData\Roaming\Adobe\Adobe Photoshop (Beta)\Adobe Photoshop (Beta) Settings

Launch BETA Photoshop While Pressing The Keyboard Shortcut
With Photoshop closed, press and hold Shift+Ctrl+Alt (Win) / Shift+Command+Option (Mac) on your keyboard and then Launch Photoshop the way you normally would.

It may help if we could see your Photoshop beta System Info. Launch Photoshop beta, and select Help >System Info...and copy/paste the text in a reply.

Another option is to use the CCD cleaner and make sure there isn't an issue there:

Hi team when I open beta software it shows.
Please fix this as soon as possible.

Thank you.

@ValeriiN , @pravin_8151 

I saw a thread where an Illustrator had an older version of the Beta, and an update fixed it. We will be having an update soon, so you may be able to try that.

Elsewhere, I've seen some customers have success with this error by reinstalling their video drivers (nVidia).

If neither of these options work, can you tell us what version of the OS you are using?

[defaulty32ergwbmcne]

Just commenting to bump this because I've encountered the exact same issue this morning. I've done the recommended fixes and I get the error in both the Beta, and the standard version

Running Windows 10 Enterprise
On an intel core i5.

@defaulty32ergwbmcne , could you please share the output of your Photoshop > System Info? Does your system support SSE 4.2 and AVX?

[Grant37764334mfju]

I've not changed anything, other than PS has updated, which I assume is the issue, but I can't get PS to open. Everytime I try I get this message. 

I've tried just about everything I could think of, uninstalling & re-installing etc. 

Does anyone have any tips or having this issue as well?

[derekwatson]

Have you tried the Adobe Cleaner Tool?

@Grant37764334mfju this issue has been reported in the beta forum

[stevenw3666982]

Happening here too...Costing me money because of this mistake.  They need this fixed right now

[Grant37764334mfju]

Yeah I tried that, didn't solve it for me unfortunately

I have tried all the ways that have been suggested, nothing helped me.
I don't have time to reinstall Windows or change something in my PC system 😔
So I installed the standard version of Photoshop and work in it for now.
I will wait for a new update of the Beta version, I hope everything will work in it 😊
The last time I had problems with After Effects, this is the way that helped me 😅
Anyway, thanks to Adobe team for trying to solve this dilemma 🙂

[Mark.Dahm]

dxcore is a Microsoft dll and it seems like a new dependency for Ps. Investigating.

[CShubert]

Have passed this on to the team.

Thanks,

The same thing has been happening to me as ValerriN for a couple of days now. I've tried all the solutions you suggested and nothing works. I hope you fix it soon. Thank you very much.

Confirmed this appears to be some kind of regression bug. Used to happen with Ai, now with Ps.

Windows Server 2019 1809

SFC returns no corrupt system files.

[andy_7488]

The last update that was installed just before this happened was MS KB5046615 & MS KB5046540

After these updates Ps stopped working.

[andy_7488]

Also oddly noticed that dxcore.dll is now missing from c:\windows\system32\ folder.

I looked at another machine and can see dxcore.dll is there still.

Anyone who is having this issue, can you report the existence of dxcore.dll in your system32 folder?

Virus scanner does not report removing this file...

[andy_7488]

Can you cross reference this issue with the Ai product Team. This was happening a few months back and then it was "fixed". 

Oddly the machine where this started happening also is now missing dxcore.dll but on a machine without Adobe, dxcore.dll is there. Perhaps the Ai team removed the dxcore.dll dependency from the app, which was not rolled forward to the Ps app?

[Mark.Dahm]

We're investigating whether we modified our dependency on that dll. It's a system level dll, and it's possible, given what @andy_7488  said, may have been changed with a Windows update. I wonder if rolling back the update might restore things? If that's too much to stomach, I'll update here when we wrap up our investigation.

Noting that this seems to be affecting pre Win 11 systems; nobody saying their Win 11 system is affected, as far as I know so far.
