I have the office hash for the file it's $oldoffice$4*XXXX*XXXX*XXXX so going by the guides i found here, I've tried
on windows, from command prompt
hashcat.exe -m 9800 hash.txt -a 3 -w 3 ?b?b?b?b?b
however the final result i get back from it is:

A point in the correct direction would be helpful.

Two questions
- Am I following the guide correctly. It's an office 4 file so that suggested i use -m 9800 (or should i use 9810). I was following this : https://hashcat.net/forum/thread-3665.html
- I kept getting the error on finishing the job: LLVM ERROR: IO failure on output stream: bad file descriptor
that came back with
