April 2, 2021, I had to uninstall and re-install the software due to error code 1603. I encounter the same problem today and really do not want to save my file again to a folder, uninstall the deluxe software and re-install again. After reinstalling the software, I still had to manually add back the tax returns I completed. Too much work. Never had this problem with previous TurboTax products.
