Windows 10: Fatal error 1603 when trying to update Turbotax 2020

I have been researching this issue and really nothing has worked. We installed Turbotax 2020 on my Dell Windows 10 laptop. Installation went fine and was put in the recommended C: drive folder. We ran the program and a dialog box comes up which wants to update the program and forms. We run that routine and after a minute or two, it finishes with a Installation failed and a fatal error 1603 message. Running the resolution box comes back no resolution to problem found. Then the program is basically locked up and you must use Task Manager to close it.


Turbotax 2020 will not run unless the updater is run successfully so at the moment I have an worthless piece of software that has been pretty reliable for me for last 15 years.


We are making sure all the latest Window 10 updates have been run and have run a repair utility on the Turbotax software. So far nothing seems to have worked.


Is this a Turbotax problem or a Windows 10 problem and is there really an answer to it?

Error 1603

Error 1603 generally occurs due to installation errors or corruption of the setup during installation or uninstallation (in most of the cases) although there are many other reasons too. And for this reasons only there is the popping of the "ERROR 1603" dialogue
box. Here are some of the ways to fix the problem :-

1. Close Background Software
2. Check the Software Is not Already Installed
3. Check That There’s Enough Hard Drive Space for the Program
4. Open the Program Install and Uninstall Troubleshooter
5. Erase Temporary Files From the Windows Temp Folder
6. Restart the Windows Installer Service
7. Edit the NtfsDisable8dot3NameCreation Registry Value
8. Grant Full Control Permission to Installation Drive

Hope the following steps would help you to recover your p.c...
