Hi, I'm not sure this will help you, but I had the same problem. My Windows XP CD was brand new and all was OK until this weird message "installation failure" requiring a ASMS file... And now I know how to go through this problem : just change your DVD drive for a CD/CDR drive. And it works! Don't ask me why, this is really strange. You can re-install your your DVD drive later, and it will still work. I hope this will help you. Have a nice day!
