How do I install 2024 and keep 2023 working?

I am nearing the end of a project in 2023 pro, but would like to test 2024 and my extensions for stability before I start my next job. Is it possible to have both 2023 & 2024 versions installed & if so how?

Full year updates install separately, they don’t update the original like incremental updates.
So install 2024 and 2023 will be untouched.


Thank you. I will go and download…
