IMPORTANT

Because Office 365 Professional Plus is installable on up to 5 PCs or Macs and has a feature that can remove an existing license and reissue it to a new device unlimited number of times, it is best to use our offline installation guide to download the offline installer and then save it on a USB flash drive for future installation on other devices. This will eliminate the need of having to download Office 365 anew every time you install or reinstall.

If you have already installed Office 365 and you are certain it is a genuine copy, all you need to do is to sign in using the credentials we issued to activate your office. Click this link and read from step 6 of both the PC and Mac installation guide on how to activate Office by signing in. 

If you own previous releases of Microsoft Office below the 2016 version, it is of utmost importance that you remove them first before installing Office 365 Professional Plus to prevent application errors. Microsoft Office is designed in a way that it only allows one installation and once license to exist in a single device. Pirated Office should also be thoroughly removed to ensure that the new installation can connect to Microsoft’s activation servers for activation.
