Missing CorelDRAW Serial Number

Hi, I am just wondering if anyone can help me. I am repackaging CorelDRAW for network installation.  I have amended the registry keys

HKLM>Software>Corel>CorelDRAW>12.0>Serial

HKLM>Software>Corel>Setup>Corel Graphics Suite 12>SerialNumber

However when I run the CorelDRAW application I am still getting the error message

 

"Missing CorelDRAW Serial Number - The serial number could not be found. Please enter your designated Serial Number in order to launch the application."

Is there any other files I am  unaware of that get modified to store the serial?

 

Thanks
