To find your product key, look for the 25-character alpha-numeric code on the back of the card inside your Microsoft 365 or Office product packaging. Sometimes the product key may be printed on your retail receipt. If you purchased from a PC manufacturer, your product key will be located somewhere in your PC packaging.
Be sure to keep track of the product key used on each specific device (ie hardware serial number) email account (and password). MS has been playing silly buggers with the consumer myaccount site so they can no longer see any part of the one-time payment product key. I'm guessing they have done the same with the business side. What is product activation? Product activation is a process during which a product key is input to allow the use of the software. Activation establishes a relationship between the software's product key and a particular installation of that software on a device.If it's a retail license you can move it from computer to computer as many times as you want to, as long as you don't have it installed on two computers at once. But if it's an OEM license, it's permanently tied to the first computer it's installed on and it may never be moved to another. You can use it as many times as you want to *only* ifMS Office Professional 2013 wont let me activate stating that it has already been activated a maximum number of times. I had no idea there was a limit on this. The key has only been used on one machine but I've rebuilt it enough times that I must have hit my limit. Is there a way to fix this
Hello, I am trying to activate the MO Professional Plus 2019 provided by my employer (a small business, 10 licenses at hand). I get message that the number of licenses has reached the maximum number of installations although it is not the case (a colleague of mine uninstalled MO from his computer complitely). The license key is valid.
This sounds fairly normal for Product Key Card retail licensing. It is a terrible PITA. The product key on the card you buy is only entered once to add another license key to the Microsoft account. The only way to know which Product Key Card key is associated with each computer is by manually tracking it yourself.This is important because the KMS host computer uses the CMID to determine the number of unique clients. You can use the ospp.vbs script to check the CMID. For more information about the ospp.vbs script, see Tools to manage volume activation of Office. You can rearm five times, unless you activate Office by using a KMS host computer.
