[Edit] It now seems that there is still a bit of x86 code in the CD/download version and it's the x86 version rather than the x64 version of the Virtual C++ Redistributable package that is missing from the TurboTax installation. This is probably only going to be missing from a PC that did not have TurboTax installed for some year prior to 2023.
For 2023, TurboTax switched from an x86 build to an x64 build. Unfortunately the TurboTax installer assumes that the latest Virtual C++ Redistributable package for x64 x86 is already installed and that's not always the case. The x64 x86 redistributable package can be found here:
