Honestly, I don't know.
I have gone through the license agreement but there is nothing written in it about this specifically.
I know that various settings and the Library will be different if you buy the INT version. Many fundamental library parts are coming from the ArchiCAD.dll file and not the library so you will not be able to change those even if you use the French library with it.
So it would still probably be the best to ask your reseller, if no one else on this Forum know the answer.
