WARNING Do not upgrade to 375/376.xx drivers (for xx<48)

It seems that a lot of GPU problems revolve around specific versions of drivers. Though NVidia has their own support structure, you can often learn from information reported by others who fold.

@SombraGuerrero: A very good workaround! This could also help for gtx 1050 ti where already @snapshot made the inf mod for 373 driver.

@Hannibal13: See previous message from SombraGuerrero: You need to use a copy the nvopencl.dll from 373 driver.

Can confirm that the dll copy works on Windows 10 Enterprise with GeForce GTX 1080. :)

It did not work for me. Windows 10 Build 14986 (Insider Preview) with GTX 1080.

Are you using the driver supplied by Windows 10 or did you copy the dll AFTER installing 376.xx from NVidia?

(In general, preview editions are not supported by FAH.)

Actually checking the log I don't think it is working on Core 21 for me at all, before this driver it used to error outright and I couldn't use GPU for folding at all now I check the log I see it's doing this:

FAH doesn't even notify on the icon any more showing there's an error. So I stand corrected it is only folding fine on Core 18 atm.

You want to make sure you install the latest GameReady driver from Nvidia. The Microsoft drivers are not quite the same. Then if it fails with the enqueue errors, download the DLL from my link a few posts back and copy it into System32 or SysWow64 depending on if you're running 32-bit or 64-bit Windows.

FAH has been working fine on previous preview versions with 373.06. After the 14986 update I installed the latest driver from the GeForce Experience, then copied the 373.06 dll to SysWOW64 and rebooted. Core 21 failed as usual.

Does your registry indicate any other paths for the DLL than SysWow64?

Given that so many things on your OS are beta and a mess, that's likely. :P

Nope. I verified it before copying the DLL.

@SombraGuerrero: Thanks, the tweak worked for me! I'm running two differing machines, each with Win 10, V1607 (OS Build 14393.576) with a Geforce 1070.

Well, now that I'm home and examining things more closely, it appears that hobbz is correct. The DLL workaround only appears to work for certain core_21 work units. For other core_21 work units and core_18, the folding fails with a different error, "BadPlatformId Size." I have rolled back to a clean install of 373.06 again and all is well.............

Please Nvidia/OpenMM, save us from this misery!!

Maybe it is necessary to also copy the OpenCL.dll?

That file hasn't changed since 373.06. Now, I've started experimenting with something else too. By adding FAHClient to the application profiles in 3D settings of the Nvidia control panel, I can bypass CUDA. In so doing, so far, I have been able to fold a core_18 WU (given), using a clean 376.33 install. Core_21 still mostly fails with the enqueue errors, but I did successfully grab one over night. Gonna let the client run while at work to see if it actually finishes successfully. This is further than I ever thought I'd be able to get with my tinkering around. I realize that disabling CUDA is very suboptimal, but I figure, if there's a way we can get most everyone's GPU doing *some* work, it's better than them being expensive doorstops.

I challenge that statement. According to http://www.geforce.com/drivers/results/108326 all recent GPUs are supported by 373.06 (WHQL) except the 1050 / 1050 Ti and from the reports I've seen, those drivers DO work on both Core21 and Core18 without any hacking. In other words, the only people who have an expensive doorstop are those trying to fold with a Windows GTX 1050* (and they can probably fix it with the hack until NV/SymTK get their acts together).
