Error: "A Version of TurboTax Is Already Installed..."

The following message appears when installing TurboTax. Similar messages may occur in older versions as well.

A version of TurboTax 2011 is already installed. You need to remove it before you can install this version. To remove TurboTax, use Add/Remove Programs on the Control Panel.

The cause of this issue is when a previous TurboTax installation did not finish installing or uninstalling, leaving it in a broken state. The remaining files on your computer are detected by the TurboTax installer, which then thinks the program is already installed.

Solution

The first solution you should try, if you haven't already, is uninstalling TurboTax and then reinstalling it again. If that fails, follow these steps:

  1. Forcefully uninstall TurboTax.
  2. Manually delete these 3 folders (replace XX with the 2-digit tax year): 
    • Windows 7 and Vista
      • C:\ProgramData\Intuit\TurboTax\TYXX
      • C:\Program Files\TurboTax\[version] 20XX, where [version] is Basic, Deluxe, Premier or Home & Business
      • C:\Users\[user]\AppData\Roaming\Intuit\TurboTax\TYXX, where [user] is your user name
    • Windows XP
      • C:\Documents and Settings\All Users\Application Data\Intuit\TurboTax\MSI\TYXX
      • C:\Documents and Settings\[user]\Application Data\Intuit\TurboTax\TYXX, where [user] is your user name
      • C:\Program Files\TurboTax\[version] 20XX, where [version] is Basic, Deluxe, Premier or Home & Business
  3. Now try installing TurboTax again.
