How to check if Microsoft Office version is 32-bit or 64-bit

Sometimes in some cases it is useful to know which version of Office you are using, for example if you download Office templates and add-ins, because one of the templates and add-ins- ins only works on the correct version of Office.

Part 1: On Windows computers

If you are using Office on Mac, open any Office program such as Word, then click Menu Word (or Excel, PowerPoint). Select About Word .

On Mac there is no choice between using the 32-bit or 64-bit version of the operating system. Macs ran 64-bit versions many years ago. Office 2011 for Mac is only available in 32-bit, and Office 2016 for Mac is only available in 64-bit.
