Delphi XE LoadFromResourceName resource not found

I have created a component inherited from an image button. I have added the up and down images to the resource image list using the 'Project|Resources and Images' menu option .
the bitmaps appear in the Project Manager and it all compiles an installs just fine.
When I use the button in my project there are no errors and the button image is used when viewed in the design window.
My project compiles just fine but when I try to open the window when running the program it give an error:



the create code for the button is:

constructor TSMfcImageBtn.create(aowner:tcomponent);
var
buttonup,buttondown : Tbitmap;
begin
inherited;
try
  buttonup := Tbitmap.Create;
  buttonup.LoadFromResourceName(hInstance,'ButtonUp');
  image.loadfrombitmap(buttonup);
  buttondown := Tbitmap.Create;
  buttondown.LoadFromResourceName(hInstance,'ButtonDown');
  imagedown.loadfrombitmap(buttondown);
finally
  buttonup.Free;
  buttondown.Free;
end;
offsets.GlyphX := 0;
offsets.GlyphY := 0;
offsets.ImageDownX := 0;
offsets.ImageDownY := 0;
offsets.TextDownX := 0;
offsets.TextDownY := 0;
offsets.TextX := 0;
offsets.Texty := 0;
end;


Any ideas
