This error does not affect the return. UltimateTax is required to use a third-party DLL file to print the 5500. This print process is significantly slower than the UltimateTax print process. The error seems most prevalent when the user exits UltimateTax too quickly after printing the 5500.
(Note: The 5500 form is not available in the UltimateTax software after 2019.)
