Query: World's most frustrating software

The setup process is a disaster. Although I entered the exact model number for my Tivo Series 3, it didn't recognize it. However, it doesn't tell you it doesn't recognize it until after its too late to go back. There's no way to restart setup either and because the information is stored online, a reinstallation of the software . It just plows through the setup aimlessly with the wrong information, configuring things in the wrong way.
