Generate a Network License File in Autodesk Account:

After planning your network and installing the Network License Manager (NLM), you need to obtain a network license file from Autodesk. This license file contains important licensing and server information and is used to configure your server so that you can run the NLM.

If you have not installed NLM, click here.

Generating a network license file in Autodesk Account and validating that license consists of the following tasks:

Collect License Server Information

Generating network license files in Autodesk Account requires you to provide information about your network license server(s). Here is the information required for each server model type:

Single Server Model:

  • Host name and physical address of the server

Redundant Server Model:

  • Host name and physical address for all three servers

Distributed Server Model:

  • Number of servers in the distributed server model
  • Host name and physical address for each server
  • Number of seats on each server

Sign in to Autodesk Account

In order to generate a network license in Autodesk Account you must be a Contract Manager or Software Coordinator and have a subscription with multi-user access for the product requiring a network license, otherwise you will not see the following options in Autodesk Account.

Sign in to your Autodesk Account using the email address and password you provided when you bought your subscription. There are two methods for beginning the process of generating a license file:

  1. Click Generate Network License File under QUICK LINKS and then select your server model and the products to be added to the license file.
  2. Click the disclosure arrow to the left of a product to reveal product details. Click Generate Network License File for the version and serial number you want to add to pre-select the product for the server model you will choose. If only one product is being added to the license file, this can allow you to skip a later step of selecting available products.

Allocate Seats to Distributed Server License Files

Note: If you are generating a license file for single or redundant server models, you can skip this step.

For distributed servers, you need to allocate the available number of seats to the different servers for the products you added. Click the + or buttons to increment or decrement the number of seats for each product on each server.

Allocate seats to distributed license servers

The system will warn you if you have under-allocated (not allocating all available seats) or over-allocated (allocating more seats than are available). Adjust the seat allocations until you have used all available seats. You will not be able to generate a license file if you have over-allocated seats.

Copy License Files to a Server

After you have generated your license file, you must save it on your license server. We recommend you save your license file to the location where you installed your Network License Manager or to a separate folder where you keep your licenses. Here are example locations for different operating systems when using the latest version of the Network License Manager (




Note: The license file you generated will have a default name such as, NOSTROMO0011855170BE.lic. You can rename the license file to anything you prefer but it must have a “.lic” extension.

Confirm License File Accuracy

After generating your license file, it is important to confirm that it contains the correct information. Your license file will only work on the machine that has the same physical address as shown in the license. If the host name does not match the host name of the server, you can modify the host name in your license file. If the physical address does not match the physical address of the server you must generate a new license with the correct physical address.

To confirm the accuracy of your license file:

  1. Open the license file using a text editor (such as Notepad or TextEdit).Note: Do not use Microsoft Word or any other word processing program that might modify the formatting of the license file.
  2. Verify that the host name and physical address matches that of the server where the license is used. If it does not match, you will need to generate a new license file with the correct information. The first line(s) of the license file, beginning with SERVER will list your host name and physical address as shown in the following examples:
    Single/Distributed licenseSERVER NOSTROMO 001F5B398D08Redundant server licenseSERVER NOSTROMO 001F5B398C08
    SERVER SULACO 005056b5600a

After you verify that your license file is correct, you can close it and move to installing and configuring the Network License Manager.
