How do I know which version to download that will supports my license?

I have moved to a new Mac. I bought license on 31 Mar 2019.
I found this page to download old versions:

Which version should I download? That my license will work on?

I have exactly the same Mac. and the same OS.
On my old mac I have 3.3.62 and it's working.

On the new Mac I get this error:

But exactly the same app is working on my old app, and you force me to upgrade.

I found that when I installing the new version, it's have an option to automatically downgrade to the latest available version. Great!
