If you purchased Windows Vista OEM probably not.
Your 64 bid DVD is only 64 bit, 32 bit is a different DVD.
Contact the seller for options.
But you may need to purchase 32 bit.
One of the many reasons OEM costs less than retail.
If you purchased retail, you already have 32 bit media.
Since there is no downgrade/upgrade path between 32 bit and 64 bit, a
Clean Installation is necessary.
Back-up all important data before beginning.
