Matthew;
If you purchased retail, there should have been a piece of paper in
the package explaining how to order the 64 bit DVD and/or CDs:

If windows Vista is OEM, contact the seller for options.
You may have to exchange or purchase another license since OEM does
not have the same options as retail.
One of the many reasons OEM costs less than retail.
