Question

Microsoft Installer error: 1603, Fatal error during installation

Hello, I can't update TurboTax. I get a "Failed to install update. Microsoft Installer error: 1603, Fatal error during installation." error message. I can't get past this error to start the software. I have already tried all of the steps to install the latest updates several times already. Can you put the most recent updates in an exe file to manually install please? I have the desktop software on disk from Costco.

Thank you.
