In the Download and install window, select Other options.Ĭheck the box Download an offline installer and select the language you want to install the Microsoft 365 apps in. If you have a Microsoft 365 subscription, you'll also need to select Install Office > on the Installs page. Select the Office for business tab from above instead. Note: If you're trying to install Microsoft 365 that you got through your work or school and you already signed in with your work or school account, don't follow these instructions.
