do the disks have folders on them ?
eg:
disk1\
disk2\
disk3\
disk4\

etc?

try copying the disk contents exactly as they are to the installation folder, i can see in the code it looks for \updates \disk*\resource. etc.. (where * = a number).

also, giving me the exact output of the message it shows when it wants you to put the disk in helps too...
