How to tell if you are runnning 32-bit or 64-bit Microsoft Office 2013

By | January 9, 2013

Quick tip today.

I needed to discover whether I was running 32bit (x86) or 64bit (x64) Microsoft Office 2013 today as I wanted to install an add-in.

Determining this from the UI eluded me so I poked around the registry a little and found a nice key which told me in a flash.

The path is:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice15.0Outlook

The key is:

Bitness

The valid values are (I assume!):

x86 / x64

Mine was set to x64 so I am happy to presume that I am running 64-bit Office and not 32-bit.

Simples.

    Microsoft Office documents store results of many hours, days or even years of work of practically all office employees and most people who use their computers at home. Microsoft Word dominates the market of word processors, and most if not all documents are stored in RTF and its proprietary DOC formats. Microsoft Excel and its XLS file format dominate spreadsheet market. Most presentations are created in Microsoft PowerPoint and stored in PPT files, and most charts and drawings are drawn in Microsoft Visio and saved as VSD files. Combined, files in these formats occupy significant space on the users’ hard drives, and represent hours and hours of work, much more than any other file format. *””.
