Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
All I can tell you is that I received a DVD that is Titled: Office Professional Plus 2013 and says PC on the left and Microsoft on the right. It is a dark blue disc label. It is in a cardboard sleeve from Microsoft with the MS insignia and a black sticker on the right inside section of the sleeve that explains the need to log onto office.com/myaccount to get the product key for the disc. The agents I spoke with on the phone told me that I should be provided a PK by whatever department is responsible for the DVD. But of course they transfer me to everyone that works at Microsoft practically and once again, of course, it is always somebody else that I need to talk to until they hit everybody once then they start connecting me back to people I have already spoken with earlier on in the conversation.
The download I did of all the install files using the Office Deployment Tool downloaded whether you called the install files "O365ProPlus" or "O2013ProPlus". I used both names in the .xml file to configure the download. So either name gets you the same set of files.
