Is anyone else having trouble downloading updates to Turbo Tax Deluxe using Windows?

I am getting the 1603 fatal installation error.

If you're having trouble updating your TurboTax 2020 for Windows Individual software using the "Check for Updates" method, you can get the latest federal program update here:

  1. Close TurboTax and all other programs except this browser window.
  2. Click here to download the 189 MB update.
  3. Save the update file to your Windows desktop.
  4. Double-click the update file w_perrelsuperpatch... on your desktop to install the manual update.

We don't offer manual updates for TurboTax state software. If you need to update your state, here are your options.
