yes, in NLM (network license manager) we have setup 2 licenses from two distincts autocad 2009 SLM (getting the .lic file from the online activation tool), and it does work. I can't add on NLM licenses for autocad 2009 upgr.2006. that is the problem, or at least I don't know how to do it, because to activate the upgr license it asks for the original 2006 s/n and another code (I think it's the request code) wich I think I can get only from the menu of an acad 2006 installation.
