TT Premier 2022 and earlier were 32-bit and I had ZERO problems even under Windows 64-bit OS. 2023 programs are all 64-bit and will only run on Windows 64-bit OS. Windows 10 64-bit has extra security and I need to run TT 2023 as an administrator or else the program will close. Starting a new return will close the program. Also, Help -> About -> Version will close the program. Warning to users who experience the program closing.
