amd64?

You can try compiling from source. Furius ISO Mount is very easy to compile.
This will make your own personal deb file.
First you need to get some prerequisites (this assumes you are using Ubuntu):

sudo apt-get install fuseiso build-essential checkinstall

Next, to compile, run the following commands:

wget http://www.marcus-furius.com/files/FuriusIsoMount/furiusisomount-0.8.0.0.tar.gz
tar xzvf furiusisomount-0.8.0.0.tar.gz
cd furiusisomount-0.8.0.0
./configure
make
sudo checkinstall

You will be asked a few questions, but you can answer the default for them all. Finally press return and Furius ISO Mount will have been compiled and installed.

Please let me know of your out come.

yes i use Ubuntu Hardy Amd64

sudo apt-get install fuseiso build-essential checkinstall <-- OK
tar xzvf furiusisomount-0.8.0.0.tar.gz <-- OK
cd furiusisomount-0.8.0.0 <-- OK
but ...

./configure
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for pkg-config... /usr/bin/pkg-config
checking for a BSD-compatible install... /usr/bin/install -c
checking for mcs... no
configure: error: mcs Not found

not working

i then installed mono-mcs
and it configured successfully
also make and sudo checkinstall worked fine

but the application is not working :(

is seems to mounts the *.iso image successfully in my home dir but all it does is creating an empty dir inside my home dir

here is the output errors from command line
---- terminal output start ---
dimitra@igna:~$ furiusisomount
fuse: failed to open /dev/fuse: Permission denied
xdg-open: unexpected option '-u'
Try 'xdg-open --help' for more information.
---- terminal output end ---

here is also a screenshot link
