Get your taxes done using TurboTax

After trying many of the steps outlined in the other posts with no success, the TT support person (AnneMarie) had me manually delete all of the prior installations with the following instructions.  It appears that an auto uninstall does not remove a problem file to allow you to do a new installation like the install on new machines that has worked for other people.   Make sure that you antivirus and firewall are turned off as well (but restart them as soon as you are done with the installation).

Forcefully uninstall and reinstall TurboTax

Sometimes, uninstalling TurboTax via the usual methoddoesn't completely remove the program.

In those instances, you can forcefully uninstall TurboTax to ensure all TurboTax files are removed.

Solution
  1. Browse to the following location on your hard drive: C:/Program Files (x86)/Common Files/Intuit/TurboTax/TY19/PER/MSI (replace XXwith the 2-digit tax year of the TurboTax program you want to uninstall, for example 18 represents TurboTax 2018).
  2. Right-click each file in this folder and select Uninstall.
  3. Delete the following directories (where XX is the 2-digit tax year of the program you've just uninstalled):
    • For Windows 10/ 8 / 7 / Vista 64-Bit
      • C:/Program Filesx86/Common Files/Intuit/TurboTax/TYXX
      • C:/Program Filesx86/TurboTaxTYXX
      • C:/Users/[Your username/]AppData/Roaming/Intuit/TurboTax/TYXX
      • C:/Program/Data/Intuit/TurboTax/TYXX
    • For Windows 10/ 8 / 7 / Vista 32-Bit
      • C:/Program Files/Common Files/Intuit/TurboTax/TYXX
      • C:/Program Files/TurboTax/TYXX
      • C:/Users/[Your username]/AppData/Roaming/Intuit/TurboTax/TYXX

    • For Windows XP
      • C:/Program Files/Common Files/Intuit/TurboTax/TYXX
      • C:/Program Files/TurboTax/[version] /20XX – replace [version] with Basic, Deluxe, etc.
      • C:/Documents and Settings/All Users/Application Data/Intuit/TurboTax/TYXX
      • C:/Documents and Settings/[Your username]/Application Data/Intuit/TurboTax/TYXX
  4. When finished, restart your computer, and then install TurboTax.
