Can a 64 bit OEM licence key be used for the 32 bit version? (This is
OEM, not retail). If it can then I only to borrow the 32 bit media from
somewhere, but web searches give conflicting advice.

have you tried the key, I think they should be interchangeable (http://

They are for the retail versions, they may not be for the oem versions.
