I just bought a new HP (July 2, 2021). It has the latest Window 10 operating system. I downloaded my TurboTax 2020. When I launched the activation window came up but was blank. From previous comments, I changed my display resolution from 1920x1080 (recommended resolution) to a lower resolution. This allowed me to see the activation window and put in the activation code. I hope TT gets this fixed for the current software and for 2021 software.
