Thanks. I'm not sure then. I am, to be honest, a little fuzzy on what a "single-install version" is.

I can tell you that my machine had a fresh install of Windows 10 last February, done by our IT person at my job. She also installed a licensed copy of Office 2013. Since then I have only used Word and Excel.

Fast-forward to last Tuesday. At the request of my client I downloaded a 30-day trial version of Office 365 from Microsoft:

https://products.office.com/en-us/try

It came with: "Fully installed Office 2016 versions of Word, Excel, PowerPoint, Outlook, and more."

So whatever you call these two things together. Meaning my Office 2013 and this new Office 2016. FWIW, I would assume that MS doesn't expect prospective converts to 365 to uninstall their existing Office installations prior to "trying" 365.

In any case, Office 365 can't seem to keep its mitts off my Word 2013. I always have to step in and shoo it away.
