Office 2010 package

Office 2010 package

I am trying to create a office 2010 package I have created a .msp file by following the documentation on how to create this package.  Under the part adding the package in Desktop Central it says Specify the Preinstalltion script as : 7za.exe x-y "Office2010Pro.7z".  I am unsure where do I specify this this script.  I tried it under pre deployment activities but got an error saying that it couldn't find the script.
