You can't run the install of a 64-bit version from within the 32-bit
version. Your only option is to boot off the 64-bit version DVD, and do a
custom install. This will allow you to install a new, clean copy of the
64-bit version.
Before you do any install, please back up your computer. AND, may I strongly
suggest running the Windows Easy Transfer (WET) program before you attempt
this. WET will allow you to save off both data and settings to a safe place
and then restore them to the new version of Windows when you rebuild as a
64-bit machine. (note: WET will not move applications -- you have to
reinstall all your applications after the install of Windows completes --
but it _will_ give you an up to date report of what applications are
installed and which ones still need to be installed.)
