Before you start
- No other version of Microsoft Office may be installed on the computer. Remove earlier versions completely.
- You need an internet connection for the download and the activation.
- Microsoft Teams is not part of the package and is installed separately.
- Have the product key you received by email to hand.
Important: remove leftovers from earlier versions
If an old installation is left behind, activation often fails. Uninstall Office from the control panel, then clean up with the Microsoft tool.
This also applies to versions that were already on the computer when you bought it: Microsoft 365 trials, a pre-installed Office 2024 preview and OneNote installed separately. All of it has to go before you enter your key.
The old Microsoft removal tool completely deletes every Office version from 2010 up to Microsoft 365, including the leftovers a normal uninstall leaves behind.
Download the removal tool Opening the file starts a wizard that walks you through the removal. Restart the computer once when it is done.⬇️ Download
Choose your language – we recommend the 64-bit version (suitable for practically all modern PCs).

This guide takes you step by step through the download, installation and activation of Microsoft Office 2016 Professional Plus – clearly explained, with real screenshots.
Installation & activation in 9 steps
Download the ISO file
Download the ISO file from the download table above. Choose your language and the matching version (32 or 64 bit). This ISO file is the basis for installing the product.
Open the ISO file
Double-click the downloaded ISO file. When the security warning appears, click “Open”. The ISO is mounted automatically as a virtual DVD drive.
Start setup
Open the virtual DVD drive in File Explorer and double-click the “setup” file.
Confirm User Account Control (Microsoft Setup Bootstrapper) with “Yes”.
Select the installation
Click on “Install Now” to start the standard installation.
Wait for the installation
Wait until the installation is fully completed. This can 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 on “File” at the top left.
Then click on “Account”.
Enter the product key
Click on “Change product key”.
Enter your 25-character product key and click on “Install”.
Confirm activation
Confirm User Account Control again with “Yes”. Your Office is now activated.
If the message “The multiple activation key limit has been reached” appears during activation, there is no reason to worry: your product key is still valid. The activation simply has to be confirmed manually once via the new Microsoft portal.
In this case, carry out the phone activation via the new Microsoft portal. You will find the complete guide here: Phone activation via the new Microsoft portal
In the portal, enter the installation ID shown in the activation wizard. The portal then generates a confirmation ID: enter this code in fields A–H of the wizard (see illustration) and click on “Next”. Your Office is then activated successfully.
