How to copy Zoo Tycoon

[TLT]

I need to copy Zoo Tycoon but I'm having problems...
I burned it with Clone CD and gave a error during the installation....
I burned with WinOnCD and said "Media Authentication Failed", so the setup.exe is protected... now I don't now what to do...
I read a earlier post saying that is a Safedisc ZT protection and LDLL.dll was the problem with the setup giving errors... but how can I change this file?

If anybody can help, thanks...
