Hi Simon, Most distributions comes with 32 and 64-bit libraries for the x86_64. For fedora, 64-bit libraries are in all the lib64 (/lib64, /usr/lib64 etc) directories and 32-bit libraries are in the usual lib directories (/lib, /usr/lib etc). There's no problem running 32-bit applications in a 64-bit OS as long as all the libraries that the application needs are available in 32-bit and the path is in /etc/ld.so.conf. The linux library linker is smart enough most of the time to find the appropriate libraries for the application. Most of the time, at least.
