Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi. I have a laptop that preinstalled Office 2019 Home & Business package. The product key also given with laptop with the product key box (no CD). After system crash I have reset the PC and now I wanted install Office 2019 Home & Business package. I have Tried to download the software using the Product key but it says This product key has already been used.
Nipon, It sounds like you actually purchased a retail version of Office Home & Business 2019 and the vendor installed it for you, rather than the Office came pre-installed by the manufacture. Whichever is the case you cannot use the Product Key more than once to install Office 2019, that is for the first time.
You will either need to see what Microsoft Support can do or the vendor. Or if Office came preinstalled by manufacture see the manufacturer. Please come back with more information to see if we can identify what you actually purchased.
