After 3 phone calls, I finally got Office Professional 2019 downloaded onto my computer. The directions sent with the email containing the product key were NOT correct for my windows 10 PC for some reason. What the instructions were telling me to do was not available so I ended up calling. While the technicians were helpful, they would only give you one step and say, "if that doesn't work, call back"... STAY ON THE PHONE THE FIRST TIME UNTIL THE PROGRAM IS INSTALLED!
