ImageEnView1.IO.Params.JPEG_Scale := ioJPEG_AUTOCALC;

if (OpenImageEnDialog1.Execute) then

I suggest you obtain the latest version and reinstall. I do not know anything else you can do, other than removing ImageEn and reinstall your current version. Having said that, I never had any problem trying to do something as simple as this with any version of ImageEn since version 1.x.

Have you tried the demos?

procedure TForm1.btn1Click(Sender: TObject);
begin
  if (OpenImageEnDialog1.Execute) then
  begin
    if FileExists(OpenImageEnDialog1.FileName) then
    begin
      ImageEnView1.IO.LoadFromFile(OpenImageEnDialog1.FileName);
      ImageEnView1.Update; { This ususally is not required, but in your case it might} 
      if ImageEnView1.IO.Aborting then
      begin
        MessageBox(0,
          'There was an error opening the image.  The image can not be opened.',
          'Error', MB_ICONWARNING or MB_OK);
        Exit;
      end;
    end
    else
      MessageBox(0, 'The image can not be opened.  The file does not exist.',
        'Error', MB_ICONWARNING or MB_OK);
  end;
end;
