From what I remember, Windows 7 does not allow applications to access the IO Ports like COM and LPT without special permission. For this you need to download the IOPort.sys driver along with a software to install and run it. I remember downloading it from an MIT website. I cant find it now, but just about any ioport.sys download should work. Also take care to run the softwares in administrator mode (right click and run as admin).
This should be of help. Otherwise I see some results on google for the same problem, look around.

Read this page on Microsoft's website. Someone posted a question about this same error code and there are some suggestions that you should try.
