How to install old SU version for Mac OS

Hello. I want to ask you if there are ways to install old SU versions for Mac OS High Sierra… If someone have one, please tell me. Thanks!

The current version of 2020 should work with High Sierra. If you want 2019, 2018, or 2017, you can also get those from the downloads page:

Activating the one you download may be a challenge, depending on your license and which version you have previously activated.
