that same application with same data i am running in my system and everything is running fine.
Then you need to start looking at what is different.
Assuming you can't use the debugger on the system where it id failing, you will need to manually add logging info to your application to narrow down exactly where the error is occurring, and then concentrate logging there to find out what data you are talking about, and how it different from the same run on your system.
Try logging to a file with File.AppendLine and compare the outputs of the two systems: look for where they differ and compare that with the code.
We can't do any of that for you: we don;t have access to either computer, or any idea what your code or data look like!
