I downloaded the iso file but cannot get it to run i xp. Any ideas?
AVG found this as a virus. Sad. Maybe you should upload it to VirusTotal.com to see what antiviruses pick this up as a bad one.
Norton identifies this file as "The program then sends extracted password hashes to a remote computer.". securityresponse.symantec.com/security_response/writeup.jsp?docid=2005-032616-0025-99&tabid=2
Excellent on Windows XP-Pro .... It could NOT crack Windows Vista Home Premium SP-2
Downloaded the Vista version. Made no changes. Set up two Vista computers (current via windows update) set up 5 simple passwords on both, example: xz489s...nasty0 etc. It was unable to crack ANY of them... Might have benefited from more tables but there is no way to do it although there appears to be a function for it, the tables don't seem available. Frankly, It is very hard not to question the validity of so many positive reviews when the software was unable to crack a single thing on my two computers.
really helpful and easy to use, except that i have no idea why is a hash, how to make one, and how to make this program work, as the guide i found was for a not-so-fresh version, and noone can help me
