How to setup Network License Manager (LMTOOLS)

September 22, 2016 By Patrick Revel Leave a comment
Todayyou will learn  how to setup a Network License (Lmtools) on your server. Please follow the instructions below and you will be on your way to using your newest Autodesk product.

  1. First you will need to see if your computer is a 32 bit or 64-bit machine (Mac and Linux users can skip this first process). There are two ways to check your system. One way to check is to click on windows explorer, and on the left-hand side right click on "This PC"(Windows 8+), "my computer"(Windows 7) and select properties.

This will bring up the Systems prompt where you will find out what System type you currently have.

A shorter way to get here is to go to start/search/type in "system" in the search field and hit enter. The System box will display.

  1. After you learn your System type, you will then need to proceed to this website you'll then choose which Operating System you're running (Windows, Mac OS X, or Linux) and then choose the System type (32 or 64 bit). Install "nlm?.?.?_ipv4_ipv6_win??.msi"
  2. After the .Msi finishes downloading, you will proceed by clicking on the .MSI download. You will then be prompted by the Autodesk Network License Manager, click Next and stop.

At this point, you will need to choose the location of where you want Lmtools to go. Personally, I would leave the location as the default but if you don't have enough room on your "C Drive" then you can install it on your "D Drive" but make sure whatever drive you choose that it says "?:\Autodesk\Network License Manager\.

Once you know the location, you can complete the install.  Then continue by clicking next until the installation is complete.  Finally, close the program

  1. Congratulations! You now have LmTools Utility installed and you are half way finished. Now you will want to open the file location.  To do this, right click on "lmtools utility".  The icon was placed automatically on your desktop. See the attached screenshots below. 

Once you have clicked on "Open file location" you will see five files inside the folder (adskflex.exe, Licenseadministration.pdf, lmgrd.exe, lmtools.exe, and lmutil.exe).  These five files are very important so please do not delete them or you will have to restart from the beginning.  Deleting these files will corrupt the lmtools.

  1. Double click on Lmtool.exe.  Once lmtools is opened, you will start on the "service / license file" tab. Pause on this tab for a split second because you will want to put a check in the box that says "Lmtools ignores license file path environment variables". We are checking this box because users who have environment variables on their computer can block lmtools and can block themselves from being able to pull a license.                                                       
  2. After you have checked the box, proceed to the "System Settings" tab. Here you will find your "server name"(computer/hostname) and "mac address"(Ethernet address). Two items of importance are the purchase of the newest version or upgrading to the newest version because we will have to write you a "License File". In order for us to complete this task we require  two pieces of information.

If you do not have a new license file, then please choose one of the following contact options to open a case with us so that we can create the license file for you.

Once you have received the new license, you can proceed on to step 7.



  1. Setting up your new license. Click on "Config Services" tab.  On this tab, at the very bottom, place a check in both  "use services" and "start server at power up" boxes.

Click on the browse box to setup the path to the lmgrd.exe file. This will bring up the location of your lmgrd.exe. Select "lmgrd.exe" and then choose open.

Choose the next browse box to setup the path to the license file.  Save the license file inside the same folder with your other five important files inside the network license manager.

Click on your license file and then click on open.

Choose the last browse box to setup the path for your debug log file.  Once this is open, type debug inside the file name and then click open.

Now, click the "Save Service" tab on the far right, and click "yes" to accept.


  1. We are almost finished setting up your Network License. Please proceed to the "start/stop/reread" tab.


On this tab, click on "stop server". At the bottom, if the server stopped correctly it should read "server stopped" if this is the case, please proceed by clicking on "start server" which then should say "start server successful".

If you tried stopping the server and this message does not display on the bottom, try starting the server again. If it fails, place a check in the box that says "Force server shutdown" then stop the server again. Attempt to start the server until you get the display box at the bottom that says "start server successful".

  1. Once your server is started successfully, proceed to the "server status" tab. On this tab you will  click on "perform status enquiry".  This will tell you which license file is in use, which programs are in the license file, how many seats are checked out and/or available, and to which users they are assigned. 


Congratulations!  You have officially finished setting up your Network License Manager.  You can now proceed to use your Autodesk products.
