ERROR: clCreateContext() : -2 : CL_UNKNOWN_ERROR
I found out myself what is the problem.

As I assumed above, unfortunately, all latest Intel OpenCL runtimes from 14.2 and above require a Core processor or higher, meaning SSE4.2 or higher.

In order to use Intel OpenCL on SSE4.1 (Core 2 Duo) you have to use OpenCL 2012 (!) runtime.

For 1st generation Core 2 Duo (SSSE3) you have to go even on older versions.

One other solution could be AMD APP SDK which supports even SSE2 processor, but hashcat complains that it is not native for Intel processors.

I'll try both solutions on my older SSSE3 Core 2 Duo to test them.
