I am sorry you are having difficulty with your purchase. If you are trying to register TurboTax CD/Download version, and it's not working, you can ignore it as it is not required to use the program.
Most installation issues can be resolved from uninstallation your software and reinstalling from the download version. Please see link below for you to download:
