    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

    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.....

    I got the latest version of ophcrack LiveCD for windows 7 to recover my password, should I ever have to. However, even booting it in Graphic mode, it does not boot into a desktop setting. Instead it is still completely text-based. Likely it does not recognize my graphics card. However, even in text mode it does not display my passwords, instead only displaying a row of dots. it does, however, display hashes for the passwords. But hashes don't actually give me passwords. I'm currently running a 2012 HP build with the most up to date version of windows 7 Home Premium.
