I had the same problem on a new Dell Inspiron 7706 2n1 with 2560x1600 display resolution. It got stuck on the activation screen. Seeing the hint to change display resolution, I tried 1280x1024 since TurboTax installed on my other computers with that resolution. It did not work on my Dell. Then I tried 1360x768 and it worked. Thanks so much for the display resolution fix suggestion.
After completing the activation, I changed back to 2560x1600 and TurboTax runs just fine. Go Figure!
