Downgrading Windows 7 from 64 to 32 bit

[riredme]

I want to downgrade Windows 7 to 32 bit so that I can run my older work software, but I cannot find the VAIO drivers for 32 bit.  Where should I look?

You will be more likely to find an answer (if one exists) if you say which Vaio model you are looking for 32-bit drivers for.
