Hello,
Thank you to your answer.
I tested PHP CLI well, it works fine.
It is a local windows machine working with Wampserver.
the PHP version is 7.3.21.
I put all the possible authorization. I have the active php_com_dotnet DLL. on another pc, with the same config, it works fine. how to check if PHP COM works well in this case? for the office version, it's the 2019 pro plus.
I don't know what to try to make it work :( ..
