This is what worked for me today:
Try running the TurboTax software in "Compatability Mode" with Windows 8 and run as "Administrator."
1. Sign out of TurboTax
2. Right-click on the TurboTax software and go to "Properties" then select "Compatability."
3. Check the box that says, "Run in Compatability mode for Win 8" even if you are running Windows 10
4. Check the box that says "Run as Administrator."
5. Click on Apply then "Ok."
6. Re-Lunch TurboTax and the software will begin the updates.
