Could not find a valid OpenCL device
Here is another thing to try (worked for me, YMMV) - these steps require Windows 8 or newer, you can likely get them to work on Windows 7 as well with some effort.
Press the Windows Key and the X key at the same time. A menu should appear by the Windows logo at on the screen (start menu). On that menu, there will be an option for either PowerShell (Admin) or Command Prompt (Admin). Pick the one of those with (Admin) on it, and acknowledge the elevation prompt.
Type cmd and press enter - regardless of which you started, this gets you to the old school command prompt (because this instruction is easier from that).
Type cd C:\Windows and press enter.
Type dir /s opencl.dll and press enter.
You'll see something like this:
==========
Directory of C:\Windows\WinSxS\amd64_dual_rdvgwddmdx11.inf_31bf3856ad364e35_10.0.17713.1000_none_6fbc2bcdc4328b94
07/07/2018 05:52 AM 27,648 opencl.dll
1 File(s) 27,648 bytes
Directory of C:\Windows\WinSxS\wow64_microsoft-windows-r..xwddmdriver-wow64-c_31bf3856ad364e35_10.0.17713.1000_none_1bbfb77ee842133a
07/07/2018 05:52 AM 23,552 opencl.dll
1 File(s) 23,552 bytes

So there are two copies - the one in amd64 (don't worry about it having AMD in the name if you're on Intel - it's normal) is supposed to be linked from c:\Windows\System32, but on my system was not.
So I run this command:
mklink C:\Windows\System32\opencl.dll C:\Windows\WinSxS\amd64_dual_rdvgwddmdx11.inf_31bf3856ad364e35_10.0.17713.1000_none_6fbc2bcdc4328b94\opencl.dll
That will fix 64bit apps - if 32bit apps are also having a problem on a 64bit machine, it's basically the same steps on the wow64 version - but the c:\windows\system32 should be c:\windows\syswow64. And yeah, I know, its backwards - Microsoft didn't want to break scripts on the Internet, so they left the 64bit folder named System32 -- then it's "Windows on Windows 64" that lets 32bit apps run, and so they named it SysWow64. Don't worry about it too much.
I'm going to complain at Microsoft, we'll see if they care. But meanwhile, that'll at least get you up and running. Could be NVidia or something that isn't doing what they're supposed to be, I don't know - but I'll report it to Microsoft and let them sort it out.
Worked. Installing Open CL Runtime fixed this issue for Windows 7, 64 bit, Intel 5.
After installing the runtime, Daz Studio recompiled various kernnels, and the simulation in dForce was able to proceed without any further errors.
Mine worked with openGL 1.2 on intel HD Graphics 4000 with DAZ Studio Pro 4.10.x but the same setup no longer works with DAZ Studio Pro 4.11.x Public Beta
Thanks! Worked for me well
It happened to me after upgrading Windows 10 (1709 to 1803).
Microsoft doesn't reinstall the nVidia driver properly. Just I reinstall my driver (378.92) dForce works now.
I think this might be what happened to me too, dForce worked yesterday, but not after a big Win10 update. I'm at v1709 now.
Nvidia won't let me upgrade or reload the driver because it's current. I don't see how to load an older nvidia driver yet. I'm
at 388.71. I guess I'm done for the weekend! Thanks in advance for any helpful thoughts!
That was it! Reinstalling the latest Nvidia driver fixed it. dForce is back. Thanks Noah for the hint.
Hope you guys don't mind if I bump this issue.
My system specs:
Windows 10 Pro 64-bit
16GB of RAM
NVIDIA GeForce RTX 2070 with manually installed latest drivers
AMD Ryzen 7th Gen
I ended up seeing 11 copies instead of 2... not sure why and then when I tried to put in the command it
gave me an error saying cannot create file that already exists.
So if my graphics is up to date and I already have the file why is it still not registering this
opencl device on daz3D?
So, I tried everything you guys suggested. Installing the openCL runtime, rolling back to 390.77 nvidia driver, and even the thing with command prompt. Nothing worked. This last one said that openCL did not have any applications attached to it. I don't know whats going on, I just format my pc and I'm really worried here, I need to work.
I have:
Windows 10 64 bits
GeForce 620 with nvidia driver 390.77
Daz studio 4.10
8 GB ram
Intel core i7 3.40 ghz
Thanks!
the same to me too !!! I do not understand why can not use ?. for clothes simultation ...
Yeah, this is a problem for me to. I was forced to update my graphics card for the sake of other programs I was running, and the update caused dforce to stop being able to recognize "an OpenCL" device. Things had been going okay before that, and I'm not in the position to roll back the driver because I need the updated drivers.
Getting a newer graphics card, but this is a bit of a pain, since I know I have a valid OpenCL card.
Personally I think Daz Studio should do away with dforce I hate dforce I'll only buy products that doesn't allow you to have to use dforce. I can't even use dforce because of this "Couldn't find a valid OpenCL device garbage! I tried fixing it just like dbacher suggested but it didn't work for me. I was looking for a cape to buy for a character I'm creating. Unfortunately all the good capes require you to use dforce This really sucks!
What are your system details?
DAZ Studio 4.14 won't launch and keeps giving me this error. My system is:
Processor: intel(r) core(tm) i7-6700hq cpu @ 2.60ghz
Windows 10 Home 64- bit
16GB of RAM
NVIDIA GeForce GTX 960M
Exception Reason:
DAZStudio.exe caused ACCESS_VIOLATION in module "C:\Windows\SYSTEM32\OpenCL.DLL" at 0033:00000000A232171B, clGetPlatformInfo()+91 byte(s)
That CPU has an embedded Intel GPU. Make sure DS is set to use the GTX 960M - right-click on desktop>nVidia Control Panel, I'm not sure where the setting is within that.
