In your Applications folder, observe that new Microsoft Office 2016 apps have been installed on your computer.
Whenever you open any of these Office apps for the first time, you will go through a few initial steps which will activate the app on your computer. In this example, we are using Microsoft Word to complete the steps for activation.
Step 1: Go to your Applications folder and double-click Microsoft Word to open it
Step 2: Click the “Get Started” button
Step 3: Click “Skip sign in”
Step 4: Choose theme: either choice is acceptable. “Colorful” presents the more modern/updated design aesthetic of Office apps. Click the “Continue” button.
Step 5: Click the “Start Using Word” button. This also completes activation of all other Office 2016 apps on your computer.
You will be presented with this screen, where you can choose to create a new document or open an existing document. You can always disregard the “Sign in” button. (This is a feature of Microsoft Office that is not utilized and set up at this time.)
