Execute Process task: Unexpected exit code

In Executing "E:\EmailDelivery.exe" "EP12A 4" at "", The process exit code was "-532459699" while the expected was "0".
It is your process, so why do you ask this forum why it returned this exit code? The Execute Process task just compares the the process exit code with expected that you set in task properties, and reports an error if the exit code does not match.|||Thanks Michael. Turns out it had to do with the package being executed via a windows service under the local system account and not having the correct credentials for the db connection.
