Question Does anyone Know of a tool Free or Paid Microsoft Office 2016 Key Finder?

Hi Guys

I have an issue at work with a client he needs to reset his windows 10 computer. However, before we do this we need to find out what his legally paid version of office 2016 is?

We have tried the following:

1. Magic Jelly Bean ==> https://www.magicaljellybean.com/keyfinder/
2. Lazesoft key finders ==> https://www.lazesoft.com/lazesoft-windows-key-finder.html
   
3. Belarc Free ==> https://www.belarc.com/en/products_belarc_advisor

Is there any tool that can find 2016 key?

Thanks in Advance...

 

If you have an installed version of Microsoft Office 2019, 2016, or 2013 via your Office 365 subscription, you don't need to worry about product keys. Just sign in to your account and download and install the latest version of Office to your computer.

He did not purchase via the online account.
What we did was use programs and it did not find the key.
So he had to buy again.
