So it appears that on the Copy error, if I select Cancel, it will ask a question of
"Do you want setup to continue without copying file?" which has a Yes/No and regardless which I select, it will continue without copying the file and Windows XP will finish the installation and reboot and work correctly. So not sure if it's the ISO that's bad or the file already exists on the HDD expanded but may be a older version if it compares CRC.
