Identify 32-Bit or 64-Bit in Office and PowerPoint 2016 for Windows

Sometimes, you want to know whether you are running a 32 or 64-bit version of PowerPoint or Office. Yes, if you are running a 32-bit version of Windows, then there's no ambiguity in the fact that you have to be running a 32-bit version of Office. But if you are running a 64-bit version of Microsoft Windows, you may be running a 32 or a 64-bit version of Office. It is not uncommon for sysadmins and even users to run 32-bit Office within a 64-bit Windows environment. Why? That’s because there are add-ins for Office products that may not work in a 64-bit version of Office. Or you may have another reason. Luckily, it’s easy to identify 32-bit or 64-bit if you know where to look.
