Do you mean it went through the entire install process or that it stopped right after the DVD got to it's splash screen?So, I ran the md5sum and the iso that I downloaded turned out OK. I burned the iso again using the slowest speed. I rebooted the laptop and it went thru the splash screen. It then ejected the DVD and asked me to hit OK. Once I did that, the PC rebooted and started in windows 7.
I might try the 12.4 version next.
