Microsoft 365

Our step-by-step guide will help you install your new software quickly and smoothly.

If you don’t have a licence key yet, you can buy one here: To the product.

ATTENTION: If you have Office 365 pre-installed on your computer, log out and uninstall Office 365 completely. Otherwise you will receive a request to subscribe to the programme after the trial version expires – but with Office 2016/2019 Home & Business Mac Catalina you have purchased an unlimited licence (without expiry date)!


Installing Office 2016/2019 Home & Business Mac Catalina is relatively straightforward: You go to the page https://setup.office.com/ , follow the instructions and enter the supplied key when prompted.


However, before you start the installation, make sure that all existing Office products have been uninstalled. To do this, you can use the License Removal Tool for Mac. Then you can start the installation.


1. Click on the link in the confirmation email or go to our download centre, select your product and click on “Download”.


2. Log in to your Microsoft account.


3. Type in your product key.

Important: If you are not redirected and you have already clicked on “Next”, open your Microsoft profile. Log in and go to “services & subscription”. Your product should be there and you can continue with step 6.
