The 64-bit version is installed by default, unless Office detects that you already have a 32-bit version of Office (or a standalone Office application such as Project or Visio). In this case, the 32-bit version of Office will be installed instead. To upgrade from a 32-bit version to a 64-bit version or vice versa, you must first uninstall Office, including any standalone Office applications you have, such as Project of Visio. After the uninstallation is complete, log back in to select More Installation Options, choose the language and version you want (64 or 32 bit), then select Install.
