requires you to backup all your data and booting with the dvd, running the 64 bit install will format your drive earasing all data on that drive. All programs will have to be reinstalled.
If you wish to keep your current programs without reinstalling, you will need to install the 32 bit upgrade.

It's a bad idea to format a drive before an OS install.

Windows 7 installer has it's own partition tool and format feature. If you want to experience some truly odd installs, partition and format with other than the Windows 7 DVD and learn why a seasoned tech just leaves unpartitioned space for the install. You may encounter a few that do this and it works, but for those that don't want surprises, they just use the stock tools.
