That should be

  ShellExecute(0, "open", "help/help.pdf", NULL, NULL, SW_SHOWNORMAL)

or

  ShellExecute(0, "open", "help\\help.pdf", NULL, NULL, SW_SHOWNORMAL)

As the help states ShellExecute returns a HINSTANCE. If its value as int
is <= 32 then it did not succeed.

         HINSTANCE hinstance = ShellExecute ( .... );

         if ( (int)hinstance <= 32 )
		{
		// not done
		}

Well the user would only need a pdf reader.
