Make sure you have a PDF file created for ANY of those prior years, and include those when you to transfer to stuff the new computer. Those PDF tax returns can be read by you without the actual desktop software.
2019 won't re-install...too late for that year. (first year of using the installation code, if I recall)
But I just installed 2020, 2021, 2022 Premier on a New Windows 11 Computer in January, just before installing 2023. So all those years should install, as long as you have the installation code.

Other stuff that "might" make a difference:
1) IF a Windows computer, any waiting or partially-installed Windows updates are known to block installation of any year's TTX program...so if you are using a Windows computer, make sure you check for any Windows updates, and reboot even if you don't find any before proceeding with anything else
2) A couple of us have had issues with actually running 2020, 2021,or sometimes 2022, if 2023 was already up and running at the same time, so make sure 2023 is shut down first. And, I would suggest, that after installing each year, you shut down that year's software before installing the next year. And if you do want to run a prior year at the same time as 2023, be sure to start up the prior year first....then 2023 (True though, might not really be an issue for everyone)
3) When starting any particular year's installation .exe file, make sure you rt-click on the .exe file and select "Run as Administrator" That seems to help some issues.
