Autodesk IPv6 Network License Manager for Windows supports mixed IPv4/IPv6 and IPv6-only environments. It does not support network license checkouts in an IPv4-only environment.
If you have multiple servers you can install on one of them and then grab lmtools.exe, lmutil.exe, lmgrd.exe, and adskflex.exe and copy to the others, just stop and start the FlexNet services in between.
Upgrade your license servers if you plan to support Autodesk’s 2014 products.
For the FlexNet (FLEXlm) executables there is a newer version available FlexNet 11.11.1.
