Microsoft Installer Error 1648
I am currently getting Microsoft Installer Error 1648 when I start the TurboTax 2025 desktop program. As a result, I am unable to efile any returns. It seems that my state program updates happened ok but not the main program updates. I have ended my antivirus software, restarted my computer, run Turbotax 2025 as an administrator and none of these actions helped. I tried to uninstall the program but it gives me the same message - "No valid sequence could be found for the set of patches." and the program does not uninstall. Has anyone else had this problem and been able to find a solution? Thank you.
