So what are you trying to back up - your Office installation or your documents, etc.?

For your Office installation, simply download a copy from: https://products.office.com/en-us/do...944b&tab=ForPC



For your your documents, etc., see: https://support.microsoft.com/en-us/...-up-your-files

Sorry. I hadn't replied earlier to your question. I wanted to back up the Office installation itself. I was not worried about the .docx, .dotx, .xlsx files etc. that I'd created. I knew they were in safe locations on the drive.

It's all good now. Via the Control Panel, I crossed my fingers and "removed" Office 365. It took the Office 2016 along with it. And my Office 2013 now works as it did before all this. No problems.
