Yes the licence is runing on a mac but the license server is running on windows, Let me explain:

I have a license server already running in a windows server it manages  navisworks and autocad network licenses all of them running in windows.

I have added an imac to may pool of machines and a network license of autocad for mac I already have my license file up and running in my license server and every other machine is working ok, but the Imac is the one that I can make connect to the server, durin isntalation I provided de ip adress of the server and The installer ran well but I can´t start the aplication as it can´t find the license server.

I hope this is enough information, any help will be very much appreciated
