  1. you cannot change drivers to downgrade from 64bit to 32bit OS. you need to re-format the drive and install windows 32it with 32-bit key code. then you need to install all the drivers. download them from sony website.

    first make sure to create recovery discs of your original OS.

    you can also try running virtual xp mode (i think it's 32bit) if computer has windows 7 professional. get the virtual xp mode files from microsoft website (free download)


    run virtual window with vmware and install another 32bit windows .

    I'd love to know how, because that's impossible. Windows 7 32 bit and 64 bit are two different operating systems. The only way to change between them is to reinstall the entire operating system.
