HiJack Fimrware Download Procudure Not Working

I have a Windows 8 machine and I can’t seem to get the firmware loader to work on my machine. I ran the batch file, as per this wiki: http://www.seeedstudio.com/wiki/index.php?title=Hijack#Introduction. But I get the error, of a missing dll file but the DLL file is present on my machine.
