Replace Your CarbonLib File
The Problem:
When I start Word X, I get the error message "Shared library error (CarbonLib)." I tried installing the evaluation version of Word 2004 to see if that'd make the error message go away, but it didn't.
The Solution:
The intriguingly named CarbonLib is a Mac OS X system file that's needed for running some applications. This message means that CarbonLib is damaged, which can prevent you from running Word. Download the latest version from the Apple web site (http://www.apple.com/support/), install it, and then run Word again.
