32-bit PC (i386) desktop image

Can anyone tell me if this Ubuntu build should/can be installed on the Up Board? I can install the 64-bit PC (AMD64) desktop image fine but when I try the 32 bit version it does not seem to recognise it. I need to have a 32 bit build as the existing custom application I want to test on it is only 32 bit and fails to install when I use the 64 bit version.
Thanks
Thanks
