After leaving a company that supplied MS-Office 365, I removed it from my Applications folder according to instructions from the IT support. All seemed to go well. I've preserved the deleted files on a thumb drive in the event they're needed.
I would like to re-install my original MS-Office 2008 from disk onto my MBP (mid-2016) with macOS Sierra.
When I ran the installer from a copy on a USB thumb-drive (for convenience), it hung-up.
When I ran the installer from the original disk using a USB Superdrive™, everything seemed to go well until I received an error message that there was nothing to install ! ! !
Not true, I can see all the files in the Finder window.
