Exact same thing happen to me. I went from Win 10 to Win 11 and suddenly TurboTax says invalid license. It worked last year just fine to file my 2024 taxes. I am going to buy the downloaded version 2025 anyway but it bothers me i can no longer look at my 2024 taxes. And yes I originally bought from Big Home Tax. This year I will buy from local big box store.
