Hi Hesham

Copy protection hasn't been solved anywhere, resulting in solutions like
product activation and autorunning pieces of software on CDs .see
http://www.theregister.co.uk/2004/02/13/emi_admits_cd_copy_protection/ .
Your best shot is to make the excel files useless without certain
environmental things (present network station, present file, present
registry entry, ... ). You'll need macros enabled and some destructive
creaticity to do that.

HTH. Best wishes Harald

Copy the files from you current CD to a CD encrypted with PGP or a
similar high-level encryption program using at least a 2048-bit key.

Melt down your current CD.
