At the risk of sounding like Captain Obvious -- for some reason you're having trouble reading one of the files. As they said, it might be a problem with your drive or perhaps a scratched/dirty disk.
A quick google with the file info you gave didn't show that this is a common install issue, so check hardware on your end. Clean the disk and clean your drive if you know how or can get a simple tool to do it with (I used to use a disk that had a small brush attached). Perhaps Tech Support could steer you to a copy of the file to avoid having to download everything.
