You are not the only one with this problem - I've had the same problem with both 2023 & 2024 Turbo Tax premier products. If I come up with a solution I'll let you know, TT support tried to help me in 2023 by sending me a fresh copy of the installation file & inserting a message that popped up after the install but before activation, asking "did this solve your problem?". And I had to respond before the program would would continue, and then of course the activation failed & there was no way to alert them that the new file didn't work. This is very frustrating for sure.
