Same for me with Deluxe Federal and State 2024 purchased from Amazon on 1/18/25 and have tried to activate many times. Ran as administrator, same message - not connected to internet. Internet works great for all browsers. Have tried all/most security fixes mentioned in posts, including safe mode with networking, using machines running W10 home and W11pro both 64 bit, same error. This is an Intuit issue, either fix or start refunding costs.
