Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Rahmat,
Welcome to Microsoft Community and thank you for asking the question. As I understand, you’re having difficulties in activating Office Pro Plus 2013.
Office Pro Plus 2013 is a volume license unless purchased via Home Use Program (HUP). This issue is occurring since you’ve been provided with a volume license key by the IT administrator. You will not be able to activate a retail Office product using a volume license key.
You will have to contact the IT administrator at your office for further information on how to install the volume license version of Office Pro Plus 2013.
Let us know in case you have any other concerns regarding Office. Thank you.
