[C#] How can I check installed office is activated/Licensed or not?

Hi

In my UWP app, I did a functionality which display office DOC/PPT into UWP app after converting it into images through console app (use bridge feature).

Now I need to apply 2 checks in my UWP app.

1. MS Office installed or not if yes, which version installed -  DONE

2. If installed, is this MS Office activated/Licensed or not - LOOKING...

So I need to work on #2. Please suggest for same.
