Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I have found workaround with this idiotic and frustrating issue created by Microsoft. (according to some source, Microsoft intentionally create this to force us to migrate to office 365 subscription)
For those who face problem activating your office license because you have selected the wrong (already used) license from your Live ID (Who can select the correct one when all look the same?), you know that you cannot change your product key once it was selected wrongly, even if you uninstall and reinstall it again.
Fortunately there is an utility that allow you to change your product key. However, you need to first retrieve your REAL product key from your Live ID account. What actually happen is that the product key given in your license box is NOT the REAL product key. After you are FORCED to register your product key into your Live ID, the system will generate a new product key inside your Live ID.
To retrieve the REAL product key, take note of the date you have registered them (please avoid installing more than 1 license per day, else you will have difficulty telling them apart), go to setup.office.com and sign in with your Live ID. Then:
- "Install from Office.com/MyAccount"
- Select "Office 2016" Tab
- Find the license according to the date the product key is added and click "Install from a disc"
- select "I have a disc"
- Click "View your product key"
Run CMD as administrator and enter this command: cscript C:\Program Files (x86)\Microsoft Office\Office16\ospp.vbs /inpkey:xxxxx-xxxxx-xxxxx-xxxxx-xxxx (replace with the REAL product key from your Live ID, not the product key from your license box)
To reveal the last 5 characters of the installed product key (This is the key found inside the Live ID account at setup.office.com, not the one shown in the license pack): cscript C:\Program Files (x86)\Microsoft Office\Office16\ospp.vbs /dstatus
Hope this help.
