Error 1719: Windows Installer service could not be accessed

Error 1719: Windows Installer service could not be accessed occurs when installing or updating TurboTax.


First, 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.
  3. Look for "MSIexec.exe" in the Details tab and end process.
  4. Try to install/update Turbotax again.

If you continue to see this error and you're using XP or Vista, download the Windows Installer.

If you're using Windows 7 or later (or downloading the Windows installer didn't work for XP/Vista), here are 3 more potential solutions:

Run the Windows System File Checker, then try installing/updating again.

Re-register the Windows Installer: Click Start > Run > type MSIEXEC /UNREGISTER > click OK (it'll look like nothing happened). Then do the same thing except this time type MSIEXEC /REGSERVER. Now try installing/updating again.

Start the Windows Installer Service:

  1. Click Start > type Services.msc in the search box > press the Enter key.
  2. Scroll down and double-click Windows Installer.
  3. Select Manual as the Startup type.
  4. Click Start, then OK.
  5. Try installing/updating again.
