Error 1921: "Service 'Intuit Update Service' (IntuitUpdateService) could not be stopped..."

Error 1921: Service 'Intuit Update Service' (IntuitUpdateService) could not be stopped. Verify that you have sufficient privileges to stop system services may occur when attempting to update TurboTax.

This can be caused by background processes that slow your computer down, or a defect in the Microsoft .NET files on your system.

Solution

Close all open programs (including TurboTax), restart your computer, reopen TurboTax and try updating again.

If that didn't work, close TurboTax and try this:

  1. In Control Panel, double-click Administrative Tools, and then double-click Services. (Use Classic View in Vista.)
  2. Right-click Intuit Update Service and choose Stop.
  3. Reopen TurboTax and try updating again.

And if you're still getting this error:

  1. Go to the Windows Update site www.windowsupdate.com and check for updates.
  2. Download and install the Microsoft .NET Framework 3.5 Service Pack 1 and .Net Framework 3.5 Family Update (KB951847).
  3. Restart your computer if prompted to do so.
  4. Reopen TurboTax and try updating again.
