Windows Server 2003 - Unknown Publisher Issues

Hi,

I'm trying to call winSCP via the command line on a Windows 2003 server box using an SSIS package but it seems to call the program as with an unknown publisher and as such fail to run and transfer my file.
Is there any way to run winSCP as a service or have it verify for the SSIS package to run automatically and call winSCP successfully?

Thanks,
John

What does it mean "call the program as with an unknown publisher"?
Why would running WinSCP as service help?
