Thanks for your reply. I am using Microsoft Office 2000 Premium and have installed this on Windows 7, Windows 8.1 (subsequently updated to Windows 10).
Right clicking on a file + properties doesn't state any file.
Looked at Security and where you have KenB etc, I have S-1-5-21-1192***897-29853***42-353***7519-1001
If I click on a file to open it, Word closes.
