The following links point to the official download server officecdn.microsoft.com. Instead of ISO format, they come as IMG images. These files are pure backup media, and can’t be installed without a retail product key.
The IMG images are not the same as the “Single Image” downloads that used to be available from Digital River, but offline versions of the streaming “Click-to-Run” version, with all disadvantages associated with that. If your required download is not included here (such as Office 2016 Professional Plus) please proceed to the download instructions here. Hashes for many Office 2016 ISO files and installers can be found in our hash database.
