Problem - how to solve it ?

[A]

Hi,
I have a program that I compiled( with Installer) into exe for using 
on Win32 systems. It works well on Windows Me, Windows 9x but 
on some computers with Windows 2000 it causes General 
Protection Error and the programs is finished. It would be nice if the 
program wrote a line number or something similar that could help a 
user find out which command caused that General Protection 
Error. Is there any solution for that?
Thank you for help
