Installation & activation in 9 steps
Download the ISO file

Open the virtual DVD drive in File Explorer and double-click the “setup” file.

Confirm the User Account Control prompt (Microsoft Setup Bootstrapper) with “Yes”.
Choose the installation
Click “Install Now” to start the standard installation.
Wait for the installation
Wait until the installation is fully completed. This may take a few minutes.
Open Word
Search for “Word 2016” in the Start menu and open the app.

Create a blank document.
Open Account
Click “File” in the top left corner.

Then click “Account”.
Enter your product key
Click “Change Product Key”.

Enter your 25-character product key and click “Install”.
Confirm activation

If the message “activation limit reached” appears during activation, there is no need to worry: your product key is still valid. The activation simply has to be confirmed once manually via the new Microsoft portal.

In this case, carry out the telephone activation via the new Microsoft portal. You can find the complete guide here: Telephone activation via the new Microsoft portal
Enter the Installation ID shown in the Activation Wizard into the portal. The portal will generate a Confirmation ID: enter this code into fields A–H of the wizard (see image) and click “Next”. Your Office will then be activated successfully.
