I wrote a console application to create PDF ..when I am running this application from my user (like double click) it is creating PDFs

But when I configured the same console application as Windoows Service (run as User (me), as SYSTEM, As Local same result)..I am getting exception from SaveAs command

Can any body help me? Obviously it is missing some thing when the application is running as a Windows Service. What it is?

Some dll? DCOM settings? another security? what it is I can’t think straungt? Help me!!!
