InstallAware

My setup is configured to update installations silently with "no reboot"; however, when the update runs, it run silently but reboots the user's computer without a warning message. This can be pretty alarming if you're not expecting it so I want to stop it. I've looked at the code and everything looks normal to me with the appropriate message box settings. Can anyone suggest how I can troubleshoot this problem. Thanks in advance.
