Version 3.6 didn't work for me (refused to load tables from LiveCD, USB stick, or anywhere else I tried), but 3.4 works perfectly. Recommend anyone having trouble with 3.6 to get hold of the older version
While I've used previous versions of Ophcrack with success on XP, the Ophcrack 3.6 live disk failed to crack passwords for Windows 7 Professional. I also installed the 64 bit version, then selected and downloaded the available Vista tables (since no free Windows 7 tables were available), and it also failed to crack passwords on Windows 7 Pro.
I have been trying to use this program for about a month now. I tried burning it to a cd and booting up my laptop. It doesnt register. It just loads windows. It takes a minute longer to load to log in screen but thats it. If i log in, it picks the cd up as "Ophcrack livecd". I then tried it on usb. Downloaded usbboot, copied/burned ophcrack to the 8gb usb(fat32). The system sees the usb as "ophcrack livecd". i restart, open boot menu, select the usb and still nothing. It loads windows. I have ophcrack v3.6.0. I am running Windows 7 ultimate. Why is it not working? Im so sure i have done everything 100%. Please help.
