Help a total beginner: No usable dictionary file found.

Hi guys,

I'm using the 4.1.0 version on windows 10 (64kb).
I have tried everything to solve my issue but I have no solution.

Here is the command I prompt in:

hashcat64 -a 6 -m 7700 --force -o "C:\hashcat-4.1.0\result.text" "C:\hashcat-4.1.0\hashtest.txt" "C:\hashcat-4.1.0\wordlist.txt"

And here is the error message I always get:

./OpenCL/m07700_a1-optimized.cl: Pure OpenCL kernel not found, falling back to optimized OpenCL kernel
No usable dictionary file found.

Thanks a lot for your help!
