running an app from server 2003 console

I have a customer who wants to install my app on a Server 2003 member server and be able to log on to the console and run the app like it was on a workstation. The app needs to install some dlls into the \Winnt\system32 to be able to create PDFs. I doubt that this is a “best practice” and I wonder if it is even possible under Server 2003.

Thanks,
Mike
