There are many other programs that can burn ISO files to a CD. Magiciso is just used as an example because it's one of the most easy to use. An alternative might be the very lightweight BurnCDCC or another free and full blown CD writer is CD Burner XP.
Users from Windows 7 can just burn an ISO to disk without installing any additional software.
Remember that to install programs or run the self burning TRK, you have to be an administrator of your local computer.
