Of course it's not working, you hard coded the directory separator again, re-read my previous message.
Try: string path = Application.StartupPath + Path.DirectorySeparatorChar + "Help.pdf"; or: string path = Path.Combine(Application.StartupPath, "Help.pdf"); Same thing. That way, the right directory separator char will be used depending on the OS. Then Process.Start(path), and see if it works...
