If you're using Windows 10, try this solution:  

  1. Right Click your taskbar and select “Task manager” 
  2. Look for “Intuit update service” in the process tab and end process.

  2. If the task manager does not have tabs in it, select More details
  3. Select the Services tab and make sure the status next to msiserver is not Running

However, if you continue to receive this error while installing TurboTax after following the instructions in the solution, there are other issues with your system that are causing this error. See Troubleshoot Installing and Running TurboTax for further troubleshooting steps.
