Installing Network License Manager.
For a network license deployment, Network License Manager (NLM) must be installed on each network license server. 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.
NLM, which can be installed from Tools & Utilities in the product installer, uses FLEXnet® license management technology from Flexera Software. Correspondingly, each Autodesk product that supports network licensing includes FLEXnet client software for communicating with NLM on the license server. When you install the NLM files, you provide a path to a local drive with the drive letter; the universal naming convention (UNC) is not permitted. Do not install NLM on a remote drive.
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.
