I need help in showing the widget for the top header area


If your theme support header widget mean header widget area is ready for the theme then you can set in going through theme options and/or Appearance=>Widgets.

Otherwise you have to make widget area is ready for the header and have to set widgets there. For any technical query about theme functionality the best choice will be contact theme Author and let them know How to Contact your purchased theme Author, theme author will be happy to answer your query.
