championship manager 4

[smorton30]

ive just bought champ manager 4 and would like to copy it so my son can use it on his system
tried to copy using clonecd and nero but to no avail--obviously as you can tell im green to this.
could someone please tell me if and how i can do this.
nero told me game was copyrighted so dont know how .
this is genuinely for no financial reason purely as a backup so i can take with laptop and leave original at home with my son.
i would be greatly thankfull
