GPU Unable to fold on Core 18 (OpenCL.dll missing)

[Imakuni]

I'm using a Gtx 970, Driver 352.62, Windows 10 Pro.

Just installed FAH after sometime. Never really had any problem with this GPU, it would always do good. In fact, it's even able to crunch Core 15, as well as Boinc GPUGrid. However, as soon as I got a Core 18 WU (which, as I said, never gave me any problem), the WU stays stuck, with a popup message saying "The program can't start because OpenCL.dll is missing".

I tried reinstalling FAH, as suggested in the message. Didn't work, still with the issue.

If anyone can help, I'll be appreciated.

Try reloading the driver, the missing DLL file should be part of that. You need to install OpenCL support as part of any driver install for any GPU folding which uses Core_17 or later.

The Nvidia Driver download site now has Windows 10 compatible drivers. Try updating from there. Those should include the proper OpenCL files. Cannot vouch for the Win X self installed driver version.

I`m pretty sure I did that, as I had the 352.62 installation file in my PC.

Regardless, I went to Nvidia's page and grabbed the newer 352.63 (Beta) and performed a clean install, and now it seems to be working. Tyall for the help.

I can't either, but a reasonable GUESS is that since Microsoft software doesn't use OpenCL, that they saw no reason to install it for you.

You probably would have been fine to install the WHQL driver from nVidia. Personally I avoid beta drivers whenever I can.
