A friend of mine is having a challenge installing core 6. The disks pass the media check on both the target computer and another computer. Disk 1 installs properly yet when he loads disk 2 it informs him that he has loaded the wrong disk. He and I both downloaded from the same site about the same time and my disks have worked so it is not the site and he is certain in both cases he is using core 6 iso's. Any suggestions as to what he should do next? Norm
