My situation :
I inherited the management of the IT of a small company (20 PCs), they all have Office 2016 installed and activated.
I have a box of 20 license cards but no way to know which belongs to which PC.
My problem :
I have a PC that needs to re-install the system as it has a lots of corruption and wrong settings.
How can I recover the key that was installed, even if I can get only the latest 5 digits it would be enough, but now, I have tried with Belarc Advisor and it gives me a key that is unknown...
I did try that in the past but ended up needing to buy a new license which is unacceptable so now it is either I can get my License to work or I learn how to do with LibreOffice.
