How do I downgrade Zorro version?

My update period has expired.
How do I downgrade my Zorro version?
I upgraded to the latest version of Zorro S 2.56.2.
Only after that I received a notification that the upgrade had expired.
How do I downgrade if I don't have the installation file for the previous version?
Or download a specific Zorro version?
I can download only the latest version from the Zorro website.

Ask oP Group support nicely and they might give you the version you need. They probably have archives.

I can give you, but I need the permission of the Tech support department.
