Purchased a license for Delphi Professional. During installation, an error is displayed:

Why is this error coming out?

Unreliable internet connection. Try again.

always that possible, try download the ISO for offline install to avoid error like this! -- and it's more quick to install it!

later, updates what it needs!

The IDE/installer have trouble reaching the Embarcadero servers on old operating systems due to their out of date HTTPS encryption. If you're using one of these old operating systems you need to update the default Windows HTTPS encryption method.
