error installation on fedora 18 64bit

Hi,

I'm trying to install DraftSight on Fedora 18 64bit with 

sudo yum install draftSight.rpm

or

sudo rpm -i draftSight.rpm

Errore nel controllo transazione: file / from install of dassault-systemes-draftsight-2013.1.56-2.i386 conflicts with file from package filesystem-3.1-2.fc18.x86_64 file /usr/bin from install of dassault-systemes-draftsight-2013.1.56-2.i386 conflicts with file from package filesystem-3.1-2.fc18.x86_64

with Fedora 17 64bit works properly


any help would be appreciated, thanks
