The installer uses "_setup.exe" to complete some install tasks.  Is the source to this program available somewhere?

Normally, _setup.exe does its job in the background.  But when the installer is run with the /silent option, on the step where it calls _setup.exe with the "install" parameter, _setup.exe opens a dialog that asks:

"Would you like Ext2Mgr automatically start when booting?" (Yes/No)

This is unexpected because it seems like the installer has already set the appropriate registry key, so the _setup.exe program shouldn't need to re-ask the question.

So can I have the source to the _setup.exe program or a fix for the dialog box popping up in silent mode?
