Office 2010 64-bit Setup processes

Processors that are 64-bit are becoming the standard for systems that range from servers to desktop computers. 64-bit systems can use more virtual and physical memory than 32-bit systems. This lets users work with much larger data sets than they could previously, and to analyze and solve large computational problems. Microsoft Office 2010 introduces native 64-bit versions of Microsoft Office products to take advantage of this larger capacity, but many users of Office are unlikely to require the 64-bit version. For example, this additional capacity is needed only by those Microsoft Excel users who require Excel spreadsheets that are larger than 2 gigabytes (GB).

The 32-bit version of Office 2010 provides the same functionality and is also compatible with 32-bit add-ins. Therefore, the 32-bit version of Office 2010 is installed by default.

Office 2010 also provides support for running 32-bit Office 2010 applications on 64-bit Windows operating systems by using Windows-32-on-Windows-64 (WOW64). WOW64 is the x86 emulator that enables 32-bit Windows-based applications to run seamlessly on 64-bit Windows systems. Office 2010 lets users continue to use existing 32-bit Microsoft ActiveX Controls, Component Object Model (COM) add-ins, and Visual Basic for Applications (VBA).

Supported 64-bit Windows operating systems

The supported Windows operating system editions for 64-bit Office 2010 client include:

  • 64-bit editions of Windows Vista with Service Pack 1
  • 64-bit editions of Windows 7
  • 64-bit editions of Windows Server 2008 with SP1
  • 64-bit editions of Windows Server 2008 R2

64-bit Client Installation of Microsoft Office 2010

  • The 32-bit Office client is the default installation on 64-bit Windows operating systems. It is installed as a WOW64 installation.
  • Office 2010 server products (Microsoft SharePoint Server 2010, Microsoft SharePoint Foundation 2010, and Microsoft Project Server 2010) support the 64-bit edition of Windows Server 2008 with Service Pack 2, and Windows Server 2008 R2.
  • For click-to-run scenarios on supported 64-bit operating systems, the only supported version is Office 2010 32-bit (WOW64).

Architecture-specific folders and customization tools

The Office 2010 DVD sources include two architecture-specific folders: one for 32-bit systems and one for 64-bit. A separate Config.xml file and Updates folder is included in each of these folders. A 64-bit version of the Office Customization Tool (OCT) is also included. The 64-bit version of the OCT provides the same user interface, capabilities, and configurable settings as the 32-bit version.
