Ipod 5th Gen. Not recognized in Itunes, But is in "My Computer" + Immediate Eject on plug

Whenever I open iTunes, I get an error message that says, "The software required for communicating with iPods and mobile phones was not installed correctly." When I have it try to repair itself, it brings up another error message that says, "the software required for this iPod is not installed correctly. Please reinstall iTunes to install the required software." I have used Revo to remove all traces of Apple products and followed the guidelines in the Apple instructions http://support.apple.com/kb/TS1369 to no avail. I've tried temporarily disabling the firewall and my AVG software during installation and that hasn't helped. My iPod connects with iTunes on other computers just fine, so I can't imagine it's the device. I have tried uninstalling and re-installing multiple times.
