Answer 1

I think the problem is, that your application is running by an user without a desktop environment. There are detected Windows Users for something like Web Applications and this user doesn't have an screen.

You should think about extracting the Screening process in a separate program.

EDIT: Kratika doesn't want to screen the clients screen, (s)he wants to screen an other website and provide the download link.
