Can't Uninstall Realtek High Definition Audio Drive

[Mortalias]

Ok, so part of the upgrade to Windows 7 requires me to uninstall the Realtek High Definition Audio Drive. When I do it from Uninstall/Change Program (from control panel) error code 6003 comes up and says setup can't run.

I have to uninstall this drive to continue on with the process, but installshield is slowing me down. Any ideas? Thanks!
