Using the Correct Network License Manager

As with all new products, change is inevitable.  Sometimes it's not very obvious. This post deals with just such a change.  Autodesk has used FlexLM to manage its network based licenses for sometime.  It's not too complicated to setup, but it is based on two critical pieces of information, the HOSTNAME and the HOSTID.  Putting this in simpler terms, the name of the server and the ethernet address of the server.  Here is where the change occurred. Windows XP and Server 2003 used a protocol named IPV4.  Newer operating systems such as Vista, Win7, and Server 2008 use IPV6.  So what you ask, it's just a newer version, isn't it?  The issue is that the format of the address changed.  See below:


IPV6 Address:  fe80::9ac3:d037:427a:6906%10
IPV4 Address: 210.169.100.45


The network license manager that is shipped on the Product discs/downloads/flash drives is IPV4 compatible.  If your machine/host is running IPV6, your license manager will not be able to resolve the information correctly and will fail when trying to server your licenses.  


What you need to do is simply download the IPV6 compatible version of the network license manager from Autodesk.  I have supplied links for both the IPV4 and IPV6 version below.



If you need the older license tools (11.7), it can be found here:
