Question on License - Order details - I don't understand

[Hernan Fonseca]

Hello
I am trying to purchase a license, and have this 2 messages that I kindly request if someone can clarify:

We do NOT suggest installing DirectAdmin onto a server with installed data. OS detection is automatic and done by the installer

And then:

Operating System​

Please select the operating system that DirectAdmin will be installed on. It is very important that this is accurate.

I cant see any option so to select the OPERATING SYSTEM.
Please see enclosed screenshot.

How should I proceed?

How should I proceed?

You can just register. As seen in the first line, DA will detect the OS automatically.
Als if you registered your account, and login, then there will be an OS choice, however it's not required anymore normally.
