Everyone, hello there. My name is Dayna Martin, and I'm a customer care specialist. Many individuals are interested in learning how to install Microsoft Office after purchasing it from www.office.com/setup. After downloading Microsoft Office from the Microsoft Office setup website, double-click the exe program to begin the installation process. This will start the Microsoft Office installation process on your computer. It may take some time to set up, but once it is, you can start working on it.
