UIF sucks. The creator of MagicISO has violated the GPL

DaemonTools shouldn't care to add this format, and probably couldn't keep up anyways. Since it changes all the time to make sure only the paying customers of MagicISO can use the files.

You shouldn't care to use the original software, because the author is a prick.

You should use this app:
UIF2ISO by Luigi Auriemma.
go to Luigi Auriemma search in page for UIF2ISO to find the download link.

If you think I'm an idiot for posting in a forum that the author of some program is a prick, then you should read the readme of UIF2ISO, and this document: http://aluigi.org/misc/magiciso_gpl_violation.txt
