Processors that are bit are becoming the standard for systems that range from servers to desktop computers. The bit systems can use more virtual and physical memory than 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 introduces native bit versions of Microsoft Office products to take advantage of this larger capacity. For example, this additional capacity is needed only by those Difference between 32 bit and 64 bit office 2010 Excel users who require Excel spreadsheets that are larger than 2 gigabytes GB.
The bit version of Office provides the same functionality and is also compatible with bit add-ins. Therefore, the bit version of Office is installed by default. Are you looking for information about which edition of Office to install or bit?

Hardware and software requirements SharePoint Server Hardware and software requirements SharePoint Foundation Hardware and software requirements Project Server For click-to-run scenarios, the supported version is Office bit WOW64 on computers that run the supported bit editions of Windows operating difference between 32 bit and 64 bit office 2010.
The OCT files are located in the Admin folder for the x86 bit and x64 bit folders, respectively. The bit version of the OCT provides the same user interface, capabilities, and configurable settings as the bit version. A bit Setup customization file that is imported to bit OCT is converted to bit, and a bit customization file that is imported to bit OCT is converted to bit. For more information about how to use the Import feature, see Import an Office Setup customization file.
The Bitness registry difference between 32 bit and 64 bit office 2010 indicates whether the Outlook installation is bit or bit. This might be useful to administrators who are interested in auditing computers to determine the installed versions of Office in their organization.
We recommend this option. Install Office bit on computers that run bit editions of Windows to take advantage of additional memory on the bit computers.

Such databases that are created by using bit Office any version can be used only with bit Office, and a database that is created on bit Office can be used only on bit Office. Installations of bit Office will run only bit controls. Computers can have bit and bit controls installed, and Office bit can only run the bit versions of the controls.
The workaround for resolving these issues is to obtain bit compatible controls and add-ins or to install Office bit WOW. In addition to controls that load into Office applications, there are also Web-based solutions that use ActiveX controls in Microsoft Internet Explorer. Office bit editions install some Office bit client-side controls for supporting solutions in a bit browser difference between 32 bit and 64 bit office 2010 default browser on current bit Windows systems.
