    How to install 32 bit software on a 64 bit system

    The quick answer to this question is:

    Code:
    dpkg --add-architecture i386
    apt-get update
    The long answer can be found here: http://wiki.debian.org/Multiarch

    I have heard mixed opinions on this matter, but what are the main reasons someone would want to install the 32 bit version of Kali on their 64 bit PC?

    Mostly for compatibility with existing drivers and programs. Also, most of the pen testing tools do not require or take advantage of 64-bit processing (except perhaps scanning and encryption cracking). Another way of looking at this is many software have been around since 32-bit era and still need to be rewritten to take advantage of 64-bit processing.

    Respectfully I disagree with this assessment in general. Although I do agree that running Kali in 32bit is my preference as clearday alluded to, there are real world advantages to using a 64bit system. However yes you are right in so far that there is not much of an advantage when it comes to running everyday software or doing remedial task such as email or documents, listening or watching media (2 Gigs of ram does this quite nicely). But if you move into the realm of encryption, media editing, compression, password generation, scientific computing or basically any memory intensive utilization (where 8 Gigs of ram comes to play) then obvious noticeable gains are observed.

    I do agree with clearday on the statement Mostly for compatibility with existing drivers and programs. And also if you use kali 32-bit as persistence live USB, it'll work flawlessly in 32-bit and 64-bit machine.

    The quick answer to this question (in early 2016 on Kali Rolling) is:

    Code:
    dpkg --add-architecture i386
    apt-get update
    apt-get install lib32z1 lib32ncurses5 lib32stdc++6

    Not sure if "dpkg --add-architecture i386" is even still required.

    Sorry for grave digging, but this is a top search result.

    Since Wheezy introduces multiarch, the ia32-libs package in now deprecated. It is now possible to install 32bit packages directly:

    dpkg --add-architecture i386 # enable multi-arch
    apt-get update
    apt-get install libc6:i386 # install base 32bit libraries
