How to Set Up for Multi-User with a Network License

James takes you step-by-step through the process of obtaining a license file and setting up LMTOOLS.

How to Set Up for Multi-User with a Network License

You can only start these steps once you’ve received your License Certificate and it’s recommended that you have the latest LMTOOLS installed.

1. Install LMTOOLS on the server that will host the license file, from the MSI file (should be NLM.msi or NLM.exe depending on the version).
The default install location is “C:/Autodesk Network License Manager”.
Start LMTOOLS from the icon that was created.

Once LMTOOLS fires up you can get two important pieces of information the Server Name and the Mac Address from the system settings. The screenshot below shows where the 2 items are.


2. Select the route to obtain the network license file (.lic) you can call us (1.888.249.4481) to do this or “Generate the network license file” from your Autodesk Account.


In the Autodesk account you can request the network license by clicking on “More actions“.
If you are calling in, please send an email with the Server information and the Serial number(s) to:

This process can take a few minutes or a few days if there is a problem with the license.

Note: If you have issues generating your license in your Autodesk account we will have issues on our end as well, if that’s the case please let us know beforehand so we can start a case at Autodesk for you.

If you are calling in skip ahead to Step 7, as we will ask about the server setup and generate the correct license file for you.

3. Select the server model, it can be:

• Single Server – 1 server – all licenses hosted here
Single Server is the most common and is easy to setup or replace if a crash occurs.
• Redundant Server – requires 3 servers – if two servers go down the system fails
• Distributed Server – requires 2 or more servers – each server has its own pool of licenses


4. Once you select the server model type you need to pick the products you want to have in the license file. To do this pick “Select and add products to this server“.


When you select the licenses to add to the server, only the networked (old style) and Mutli-User licenses will show up in the list. Once you have your products selected (like in the screenshot below), you need to insert the Server name and the MAC Address that you received from LMTOOLS.


To remove a license simply click on the X on the right side. Once you generate the license file it is the new license file for you to use. It’s best not to copy and paste older licenses into this file – it can cause issues if the license packages have different time stamps.  If you are merging new Multi-User licenses with older network licenses, please have us check over the file to make sure it will work properly.
5. Click “Get network license file“, then save or email a copy from the license file.

Choose “Save License File” to put a copy on the computer, or click on “Send and close” (it will email a copy to the contract admin).
6. Verify the license file
Simply open the .lic file in Notepad or Wordpad and make sure there is no additional text added (unless you are using an options file.) It should look like this:
Sometimes antivirus programs will put a secure flag at the top and bottom of the file, this will prevent the license from being read.


7. After you have opened the license file to verify everything is in it and that there was no additional text, put a copy of the license file in the Autodesk Network License Manager location.
(C:/Autodesk Network License Manager)
You will also need to create a log file in this location. If you name it log.log it should be fine.
Note: Make sure you have file extensions showing otherwise you will end up with log.log.txt

8. Open LMTOOLS again (or switch back to it if you never closed it down). Change the tab to “Config Services“, it should look like this:


Next we need to name the service something that can be easily identified as an Autodesk Service. I recommend “AutodeskNLM”, after that path to the LMGRD.exe file in the “C:/Autodesk Network License Manager” location. Change the path to the license file and the log file. Select “Use Services” and “Start Server as Power Up“. Click “Save Service” once you’re done.


9. If you are running an old service on the server make sure you stop the service before starting the new one. If you reconfigured your old service to run the new license file you will need to stop the service, start the service, then read the license file. Whenever you stop the service and restart it – it’s good practice to reread the license file. This can be done on the “Start/Stop/Reread” Tab.


10. After that, check the license on “Server Status“, using “Perform Status Enquiry“. It will list all of the products that were readable in the license file. If something is not showing up it means the data in the license file is not right. (If you named the Server incorrectly and tried changing it in the license file, it will not work as the license file has encrypted pieces that reference the server name and mac address in the code.)


11. If Everything was OK in the status check, then the next step is to test it out on one of the workstation machines. If you have any errors, please contact us.
If it’s the first time you’re launching select “Use a Network License” and specify the Server when it asks. Most of the time if the workstation can see the Server it will autoconnect (in the 2017 version).


If the product was in a trial mode or a standalone where you are wanting to change to a network license you will need to use “Change License Type“. It is accessed through the “Help” > “About <Product>“> “Manage License…” > “Change license type“.
