This is the serious issue which i faced long time ago. I got a installation file which can install 32 bit operating systems. But i had to install it on top of my 64 bit ubuntu machine.every time it get failed.
Then i installed 32 bit support libraries in to the 64 bit operating system with "apt -get installia32-libs" command.
After install above libraries i managed to run 32 bit bin file in my 64 bit ubuntu operating system.
