what's the problem with 64-bits? I don't have any problem running any 32-bit apps on 64-bit windows and it should be that way.
From wikipedia:
Quotex86-64 processors can run existing 32-bit or 16-bit x86 programs without sacrificing speed or compatibility, and in addition, they support new programs written in an extended instruction set, which features a 64-bit address space and other capabilities
