This can occur when you try to perform the carryforward after accessing a function in UltimateTax that uses the Select Directory dialog box (such as Backup/Restore or reinstall state/bank software). After you close the program and reopen it, you will be able to perform the prior-year carryforward successfully.
Alternately, you can also insert the drive letter where the prior year of UltimateTax is installed in front of the Directory containing files path.
This information applies to all years of the UltimateTax software.
