How do i get a 32bit system run a 64bit

I'm confused on what you are asking here. Do you need a 32-bit program to run on a computer running 64-bit Windows 7?

If you want to move from 64-bit Windows 7 to 32-bit Windows 7, you can only do so by performing a clean installation.

Please clarify,

Hi newcomer and welcome to the Tom's hardware forum.

1- If u want run a x64 bits application in a 32bit OS that's not possible.
2- If u want run a 32 bits applications in a x64 OS u only need install it and use it.

Have you considered using XP Mode / Virtual PC? XP Mode is a 32-bit version of Windows XP and will run within a 32-bit / 64-bit environment on Windows 7 (Professional or higher).

OK so now you have a 64 bit OS, right? it should run 32 bit apps with no problems, what is the app you are trying to use, what is the OS you are using
