If I followed along correctly, it sounds like you were attempting to install Zorin OS 16 LITE, on seriously old 32-bit machines, correct?
Simple answer, Zorin OS 16, either Core, or LITE, only supports 64-bit CPU's. All future distributions, will be the same way.
The newest OS that you can install on those old computers, is Zorin OS 15.3 LITE.
This is happening because Linux support for 32-bit CPU's is being dropped, as most people have 64-bit machines now days, and its just far too much work for developers, to continue supporting 32-bit hardware.
Hope this addresses some confusion, and as a result, helps you with your solution.
