Windows 64-bit
Microsoft has just published the Office 2016 Preview application for home and enterprise. It is available to Office 365 subscribers, other Office users and non-Office users on the Office website.
If you are not an Office 365 subscriber, you can download a 32-bit or 64-bit installer for the Office 2016 Preview from the site. A click on one of the download links loads a small stub installer to the computer system which downloads the full installation package when executed on it.
Use the product key NKGG6-WBPCC-HXWMY-6DQGJ-CPQVG on the system after installation when asked to enter it. You are asked to activate Office when you launch one of the applications that ship with it for the first time. There you need to click on the “enter a product key instead” link to provide the key above and activate the preview this way.
Note: Office 2016 Preview will replace existing versions of (desktop) Office on the system. Microsoft notes that you will be able to go back to those versions if you remove the Office 2016 Preview again from the PC.
