Please advise: I bought the update 2021 ultimate to install on my new computor. I suppose that I first have to install the PD 19 Ultimate on this new computor. I have been updating from PD 14. Question: Do I have to start installing all updates from PD 14, or is it sufficient to start with PD 19? I have kept copies of the previous versions. My current computor is too old and must be replaced, but I would like advice on how to do the changeover without any mishaps.
