Hashcat 5.1.0 never returns results

[undeath]

Code:

hashcat64.exe -a 3 -m 0 -p : -o "c:\my\desktop\pw.txt" "c:\my\desktop\hash.txt" -O -1 ?a ?1?1?1?1

that's a weird "simple" example. A simple example would be

Code:

hashcat64.exe -a 3 -m 0 "c:\my\desktop\hash.txt" ?d?d?d?d

But unrelated to your problem.

You seem to have a broken OpenCL driver installed. I recall people reporting a broken Intel OpenCL runtime in particular.
