Microsoft Office 2013 and Windows 64-bit Operating Systems

Posted on Friday, March 8th, 2013 by ITS Communications under Service Enhancements.

(Note: This article applies only to those who have requested that their computer have the Windows 64 bit rather than 32 bit version installed.  If you are unsure of which version you have, check using the instructions found here.)

On 3/13/12, ITS will make the Microsoft Office 2013 32-bit version available for installation on campus General Computing Network (GCN) computers through Run Advertised Programs (RAP).  Because Microsoft has cautioned users not to install the 64-bit version of Office even on computers running a 64-bit Windows Operating System (OS) due to compatibility problems with other applications and add-ins, the 32-bit version is being made available in RAP to both 32 and 64-bit Windows OS computers.  Running the Office 2013 installation from RAP will uninstall any existing versions of Office and install the 32-bit version.  

Unlike other 32-bit versions of software that ITS does not support on a 64-bit OS, Office 2013 is designed to be compatible with that OS.  According to Microsoft:  “Office 2013 lets users continue to use existing Microsoft ActiveX Controls, Component Object Model (COM) add-ins, which are primarily 32-bit because no 64-bit versions are available yet for many add-ins. In some cases, 64-bit Visual Basic for Applications (VBA) solutions may have to be modified to interface with system APIs and other imports. Supporting 32-bit Office 2013 applications that run on 64-bit operating systems allows for better compatibility with controls, add-ins, and VBA.”  

Clients who need to take advantage of the 64-bit Office 2013 capabilities to handle large data sets should contact the ITS Service Desk at 6-TECH to arrange for a manual installation.
