[newbie] Traktopel ISO files. Install?

[G]

I downloaded the 2 Traktopel ISo files to cd's.  I rebooted but it does
it invoke them.  I went into Rot/mnt/cdrom and I see them, yet if I
click on them nothing happens, it brings up a window asking what
application i want to associate with the file.

How do i install them off the cd?
