The following installation procedure is the same for Office 2010, 2013 and 2016.
With the ISO file in a local folder, we now need to extract the file in order to run the Office installer. To do so, let’s download the latest version of 7zip.
It is a very simple and light program. Once 7zip is downloaded and installed, right-click the ISO file, and go to 7-zip > Extract Here.
Access the new folder created after the ISO extraction, and double-click setup.exe to run the Office installer.
Let the program install and run. Enter the product key when required.
Open any Office 2016 app such as Word, Excel, PowerPoint, Visio, Project, etc.
Go to File > Account.
Click Change product key.
You’ll see a window like this:
