Choosing between Microsoft Office 32-bit or 64-bit

on December 23, 2015

Should I install the 32-bit or 64-bit edition of Microsoft Office?

Microsoft generally recommends installing the 32-bit version of Office as the functionality is the same as the 64-bit version and there are less compatibility issues with other applications.  However, a relevant difference between the two is that the 64-bit version is able to take advantage of more of your computer's memory, allowing you to work with extra-large databases or worksheets.

While the extra memory the 64-bit version has available to it can be helpful if you are working with large files in SigmaXL, there are a few things to bear in mind before deciding to install this version.  For a start, a 64-bit version of Office is only compatible with the 64-bit editions of Windows 7 and Windows 8.  You will also run into compatibility issues with any Excel add-ins that do not have 64-bit versions.

SigmaXL and DiscoverSim are available as both 32-bit and 64-bit versions but you will need to ensure you install the correct version based on your Excel edition.

Install Microsoft Office 2010/2013/2016 64-bit if:

You have the 64-bit edition of Windows 7 or 8.
You often work with large databases or worksheets in SigmaXL.
You do not require Third-party ActiveX controls and add-ins.
You do not require other 32-bit only, Excel add-ins.

Otherwise, we recommend installing a 32-bit edition of Office.

Please note that only Microsoft Office 2010, 2013 and 2016 have 64-bit editions.
