Chinese Delphi Problem

I have a Delphi unit which allows you to add data to EXE files. ? It is working fine except in Chinese Simplified versions of Windows (possibly others) and I am not sure why. Under Chinese Simplified the resultant EXEs fail to run. ? When the file is used to modify an EXE in English Windows the resultant file runs fine. I have attached the unit. ? I need someone with Chinese Simplified Windows who understands Delphi to fix the unit so that it works correctly under Chinese versions of Windows. Can you help?
