Solution

This issue can occur if your TurboTax Business program didn't install correctly, for example if files became corrupted during the installation.

To resolve, uninstall TurboTax Business, and then reinstall the program.

If the problem persists, try installing from the hard drive (if using a CD) or downloading your TurboTax Business program again and installing from the newly-downloaded file.
