I have had exactly the same problem only on Windows 11. It has happened twice. I was able to fix it but uninstalling the program and it fixed the problem for me. Been using TurboTax for over 20 years and first problem I have had. I'm sure they know about the problem as I have talked to a couple other people experiencing it. So far program has worked now for 3 days but not holding my breath. As suggested I did the manual update but problem comes back. All other programs working fine and thought the expert says registry problem etc etc I am positive it's a problem with TurboTax program that they won't admit is their problem. Even reinstalled TT on a fresh install of Windows. Pain in the #ss.
