Options for installing Office 2013

Hi,
I own a copy of Office 2013 which I had installed on a previous laptop and just yesterday I spoke with MS support who gave me an activation? ID which allowed me to register Office on this new machine.

Only last evening I wiped the OEM install and replaced it with a clean Win10 base.

The problem is I'm not exactly sure how I managed to install Office in the first place. As I look around the menu now I have options to install Office 365 as a buy or trial but no link to install with an existing product key. I recall being asked to enter the registration key after opening Office which is when I received the message to activate by telephone.

If I try to install from the "my account web page" I receive errors if I enter the original product key and seemingly no avenue to enter the activation code I was given which is a 9-block code not 5.

Is there a solution to this or will I have to phone support again?

TIA

That "code" you were given probably is what usually works when clicking the Activate by phone choice and reading the series of numbers to the answering person or computer.

Yes correct. I'm confident I can re-enter the code if I could manage to install Office 2013 someway...

Do you know if I can install Office 2013 via Office 365? If I enter the activation code afterwards does it morph into 2013 for instance?

Thanks
