Sorry was just me being dumb

Ok I've followed the video I found and done everything its said AND cd to run folder SEE BELOW

C:\Users\Ben>cd C:\Users\Ben\Desktop\john171w\john1701\run

I've then entered the command
C:\Users\Ben\Desktop\john171w\john1701\run>john-386.exe -i:digits n900pass.txt
But then get this!
'john-386.exe' is not recognized as an internal or external command,
operable program or batch file.

I dont understand what the john-386.exe is. Maybe I need to change this to suit my own PC/file location or something....
