how do I transfer my previously purchased Microsoft Office applications from a seagate backup drive onto my mac?

Drag it.

Or do you want to install in on your Mac?

I tried to drag but it said it needed to be reinstalled. So I tried that, still didn't work. Called Microsoft this morning and they said I needed my purchase code

Then you will need the purchase code...

Ask on the Microsoft Mac forums as these forums are for troubleshooting Apple Software Update for Windows, a software package for Windows designed to update Apple products that run on Windows, and not related to Microsoft Office or your question in any way
