Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I had another older version office . I tried it too without any success.
But since I asked that question, I found THE solution. It is really very simple but not explained anywhere: office365 is proposed to be installed and if you ckick (2 times) to install it, you have effectively the beginning of the installation and have to pay the licence even if you have another previous version.
But if you ckick (left one) only one time on this version, you will see three possibility appear on your screen, of course the first is install office 365 but the 3rd one is "enter your key code" ... What does it mean ??? The keycode for the new office 365? NO --> I entered the key code of my previous office 2013 version and Youppie !! Windows began to search the office version which is linked to that key code. And installation is automatic and rapid. It detected that my version was a pro one and I have now the entire office 2013 available.
What I Wonder is the simplicity. What I don't appreciate from Microsoft is that it is nowhere explained by Microsoft. I think it is now a common problem that a lot of person could have due to the fact that now, only a key code is given without any installation disk when it is still possible( what was not the case for me).
Thanks a lot for your questions and the help you were ready to give me !
