I experience some issues to install OX text on OX app suite without valid license.

First, is it possible to install OX text without valid license ?
If yes, anybody can tell me where can i find a howto about it ?

I read this one :
And it seems it is mandatory to install the document converter (that is require a license) and the rendering engine, with a license too.

So i am a little bit lost on what is possible to do.

Any help will be greatly appreciated.
