I have created a fairly comprehensive unattended install process, and it works...or at least it did until I updated the service pack files for Client Access Express V5R1. Since they have been copied to the install share, the unattended install halts during file copying, right at the point when it begins to copy the new service pack files. I tried moving them to another folder, and checking their file attributes with no success. The only way to fix the process is to remove the entire service pack folder. Any help would be greatly appreciated.
