Not knowing exactly what you are encountering, but a shot in the dark.....
I haven't tried this recently....I've noticed that if I have Windows Desktop 2024 running, that I sometimes cannot start up earlier Desktop tax years. But if I shut down 2024 , I can start up any of the earlier years (as long as they were already installed and running on some prior date).

So, now I guess I need to go try it again with 2024 running...maybe TTX fixed that particular issue sometime in the last few months.
