ISO Error - I try everthing for hours

Dears

I am trying to write the ISO to a bootable USB drive, but without success. Every time I try, it gives an error.

I have downloaded it several times and even tested it on another computer, but the error persists. I can’t create the ISO with either Balena or Rufus. It always says the file is corrupted.

Another point: Is there already a bootable ISO for installation on a Xen Server or Hyper-V?
