We have purchased Autocad Education Master Suite 2013 - 125 users.


I have installed LMTools by Flexera in Server (Win 2008 R2). Later I have installed Autocad 2013 in client PC (Win 7).


Now while opening the autocad 2013 in client pc i getting the error 15.570.0 - A valid licence could not obtained.


Please anyone can u help me to solve this problem.

Welcome to the community.


Assuming that your license manager is actually running and you have verified licenses are available with the Server Status tab, then the problem is almost certainly an IPv6 and/or firewall issue.


You need to make sure exceptions are set for ports 27000, 2080, and preferably all 4 .exe files of the FlexLM. 


For more information about Network License Manager connectivity issues and IPv6, please see my discussion post here:


I assure you, this one can be fixed.
