my hash (edited for  hashcat) is like this one: ( lenght 96 characters )

It says right in the error what to do. If your computer no longer has support from its OS (windows 7) then fallback to using older versions of hashcat with NO SUPPORT on the forum. Otherwise, just do what it is saying in the CLI. Install the necessary drivers for your system to be recognized by hashcat.

yes i know that
i've ask only link to download the right driver for my laptop
found this: intel_sdk_for_opencl_applications_2020.3.494.zip. it's ok ?

also: from cmd i run only hashcat hash.txt
it's enough or need more command ?

i've read, from other thread here, that to find a password takes DAYS (with fast and new pc, not mine) ...

so i wonder what is the advantage of using hashcat against a passw cracker app like PassFab for RAR

Do you want another company having your data? In lots of cases, it is private information which is why it is passworded to begin with.
