32 bit libraries for centos 6.4

[vegas]

As always trying to get the best of both worlds with centos 6.4 64 and 32 bit architecture so I achieve what I cant with windows that is bring to the pan my old and new stuff blended together and smooothly,well I installed crossover on a physical computer is not remote at all and then when trying to install a 32 bit outfit it told me that I needed the 32 bit libraries ,anyone can tell me how to install them without using code,because using a command line can be an alternative but Im only used doing that on remote situation and since this is a physical computer I think I might need to log as root so,or doing so to paste it on sys folder aint it?,well if anyone has done that will be glad if you give me a helping hand on this thank you before hand
