The 32-bit and 64-bit Windows FAQ states:
Thus make a back-up if you want to and then reinstall, there is no other feasible way... |

The 32bit to 64bit conversion makes fundamental changes to the way your system runs that can't be done on a running system. You will have to re-install windows and everything that goes along with that. |

As a rule, switching from 32 bit to 64 bit, or vise versa, cannot be done as an in-place upgrade. Even if it's the same operating system. You need to back up your files and programs and do the whole install. |
