A number of new features and enhancements have been implemented in this release.
The Network License Manager (NLM), installed on one or more servers, controls the distribution of licenses to users. NLM can be installed from the product installer, using the Tools & Utilities option. If an earlier version of NLM is already installed on the server, uninstall that version, and then install the new version into the directory where the old version was located. NLM must configure the license servers before any products can obtain licenses and start running, but NLM can be installed either before or after the products that will use it.
If you are unsure which NLM version you have, run "C:\Program Files\Autodesk Network License Manager\lmtools.exe" , then click Help->About to check.
After installing NLM, you will need one or more network license files. Each server requires a network license file, which you obtain from Autodesk. The license file authorizes the operation of a product serial number on the specific server or servers in your network. If you have a network license serial number, you may be able to generate the license file by following the instructions at http://registeronce.autodesk.com. Otherwise, contact Autodesk.
