Subject: WIN32OLE - failed to create WIN32OLE

I am trying to create a ruby class base on a Win32 COM typelib info.
The class I tried to create is as followed.

COM Type info: (There is no registry entry for this class)

   [
      uuid(0058FFFF-5B03-11D3-A520-00805F9BE596),
      helpstring("Static members of FOHoard"),
      helpcontext(0x00580000),
      hidden
    ]
    dispinterface FOHoardHelper {
        properties:
        methods:
            [id(00000000), propget, hidden, helpstring("The type name
of this object instance (Default)")]
            BSTR Item();
            [id(0x00007ffd), hidden, helpstring("Returns a reference
to this helper instance"), helpcontext(0x00007ffd)]
            FOHoardHelper* Me();
            [id(0x00580002), helpstring("Create a new empty hoard
(collection)"), helpcontext(0x00580002)]
            FOHoard* createEmpty();
    };

Ruby class:

class FOHoardHelper
  include WIN32OLE::VARIANT
  attr_reader :lastargs
  attr_reader :dispatch
  attr_reader :clsid
  attr_reader :progid

  def initialize(obj = nil)
    @clsid = "{0058FFFF-5B03-11D3-A520-00805F9BE596}"
    if obj.nil?
      @dispatch = WIN32OLE.new @clsid
    else
      @dispatch = obj
    end
  end

  def createEmpty()
    ret = @dispatch._invoke(5767170, [], [])
    @lastargs = WIN32OLE::ARGV
    ret
  end

end

My test code:
          f = FOHoardHelper.new;
          hlist = f.createEmpty;

I got this error message:
F:/NetBeansProjects/TAVolTest/lib/CalendarUtils.rb:45:in `initialize':
failed to create WIN32OLE object from `{0058FFFF-5B03-11D3-
A520-00805F9BE596}' (WIN32OLERuntimeError)

    HRESULT error code:0x80040154


Could you give me some help?
