Failed to initialize driver version from platform...: 0 (CL_SUCCESS)

[chris_st]

Calling ioc64.exe with device=CPU results in "Failed to initialize driver version from platform...: 0 (CL_SUCCESS)".

Background: I'm running Windows 10 Education on an Intel(R) Core(TM) i7-8700K CPU, and the OpenCL SDK and the newest OpenCL CPU runtime are installed and working.

I don't get this error if I set device=GPU, then everything works fine. And I didn't get this error a few weeks ago. In meantime I've upgraded from Windows 10 Home to Windows 10 Education.

Hi,

Could you use OpenCL CPU Runtime, instead of OpenCL SDK? Maybe there are some compatibility issues between OpenCL CPU Runtime and OpenCL SDK. Could you uninstall OpenCL SDK and try again?

Thanks
