Installing 32bit application on your 64bit machine is common, but sometimes you get an error when using the ia32 libraries. You can download the specific library or as an alternative use getlibs.
When you try to run a 32 bit application on a 64 bit computer you get errors.
Open a terminal and type:
$ sudo apt-get install ia32-libs
Now You can install your application
$ sudo dpkg -i - -force-architecture yourpackage.deb
This should work in most cases.
