    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.

    I am having a problem using this version 3.6.0. When I boot this live cd it does not load the tables. It only apply brute force attack. I have used version 3.4.0 before and checked passwords of windows 7 on three systems. 2 were found and on one PC this live cd didnot showed any passwords. Then I tried this latest version 3.6.0 but it is not loading any tables to find the password. So I need help about this problem. What I can do to load the tables? Need help !!!!

    I got the LIVE disc and burned it to CDR. After one try with "automated," on Windows XP Professional, I clicked on the link to reveal the password. It said, "file not found." Fortunately, the program did show that the Administrator account had no password set at all, so I used the info to log in and reset my account's password. Everyone should know that I didn't spend ANY time on the issue and only read about 2% of what the program had to offer. I zipped on through and decided it would be much faster to use what I learned from OPHCRACK to choose the Administrator login route. <br><br>This program probably works. Thanks!

    I am trying to recover the admin PW on my windows 7 desktop. I successfully booted from a CD with the ISO on it, but it did not recover any passwords. It took me to an orange desktop and asked me to choose a partition, I tried both and neither recovered anything... did I do it wrong? Then I tried doing it w/ the install version but it asks for a hash. I don't understand how I am supposed to provide a hash for the password if I don't know what the password is.....
