Vista - Downgrading 64-bit to 32-bit

I have a Windows Vista Business 64-bit OEM license. The thing is: I´ve
noticed that some of the software I use works much better in the 32-bit
version of windows. So, my question is: can I downgrade to Windows Vista
Business 32-bit using my serial number, and then revert back again to 64-bit?

You will have to do a clean install of Vista Business 32bit. x64 allocates
hard drive differently, so you can't just put in a 32bit Vista disc and
upgrade it to 32bit. You will definitely have to clean install the 32bit.

Thank you, Sasha. But mabe I didn't explain myself properly: I know that I'll
have to do a clean install, but what I don't know is if this means buying a
new OEM license, or if I can use my existing licence (I would unnistall the
64-bit version).

If you don't have the OEM 32bit disc. Then you will have to buy another
license or go out and buy Vista Home Premium box set.

Sorry, I miss understood you.
