Can't open help page pn runtime

Hi all.
I need to open Crystal Reports help page while running Crystal Reports activex control. In my application, after viewing a report result, user can export data. In the "Export Data" dialog of Crystal Reports, there is a "Help" button. When clicked nothing happens. But when I open the report in Crystal Reports, then view sample data, and then open the "Export Data" dialog, help functionality works.
I think it's about referencing the help file of Crystal Reports from an application using activex controls. Thanks for any help.
