Clean uninstall and reinstall of TurboTax Business Incorporated

In some cases, when 2019 and 2020 are installed together or 2020 and 2021 are installed together customers may experience installation or carry forward errors:

Resolution

1. Uninstall all 2019, 2020 and 2021 versions of the software. They can be installed at a later time. Programs are uninstalled by opening the Programs and Features control panel, selecting the program and then selecting Uninstall/Change.
   
2. Navigate in the Windows Registry (type Regedit in the Windows Search bar) to the following path:
   
   HKEY_CURRENT_USER\Software\Intuit
   
   If the Intuit folder is presents, rename it with the appendix _old (for example, Intuit_old):
   
   
   
3. Close the registry window.
   
4. Rename the following folders:
   
   C:\ProgramData\Intuit\QTBInc\[YEAR OF PROGRAM].
   
   Rename the QTBInc folder by adding _old on the end.
   
   C:\ProgramFiles(x86)\Intuit\Turbo Tax\[YEAR OF PROGRAM].
   
   Rename the Turbo Tax folder by adding _old on the end.
   
   C:\Users\Name\AppData\Local\Intuit\QTBInc\[YEAR OF PROGRAM].
   
   Rename the QTBInc folder by adding _old on the end.
   
   C:\Users\Name\AppData\Roaming\Intuit\QTBinc.
   
   Rename the QTBinc folder to QTBinc_old.
   
5. Install the year of software you need at the moment in order to prevent further access violation errors. You can reinstall the other years at a later time.

When renaming folders, if you already see a folder renamed with a suffix of _old, use a suffix of _old1 or -old. The point of renaming is only to force TurboTax Business Incorporated to generate a new folder upon reinstallation.
