1) To obtain the appropriate server code for your licenses, you must determine the MAC Address of the physical ethernet device for your machine and then set the GHS_LM_EXPECTED_MAC environment variable to that hardware MAC address.   

• To determine which MAC Address is tied to the physical ethernet device, use the "ifconfig -a" command (Linux), "ipconfig /all" command (Windows) or contact your IT Department.
• Once the MAC Address is determined for the ethernet hardware, set the GHS_LM_EXPECTED_MAC environment variable using an appropriate method for the host OS with one of the following MAC address formats:
  •  B8-AC-6F-97-5A-5F or B8:AC:6F:97-5A:5F

2) Next, run the servecode executable from your MULTI installation. This is a command line program, so you’ll need to open a shell (on UNIX) or a command prompt (on Windows), then navigate into the directory from which you plan to run MULTI or the license server.

• If you plan to use Elan (legacy) licenses, run servecode -l to obtain the server code.
• If you plan to use GHS licenses, run servecode with the parameters according to the version of MULTI/Compiler you have installed:

MULTI 7 and earlier or Compiler v2018.1.4 and earlier, enter this command within the shell or command prompt:

 servecode -g -v

MULTI 8 and Compiler v2018.5.4 and later, enter this command within the shell or command prompt:

 servecode -v

The image below shows the redacted output of running 'servecode -v' in the MULTI 8.1.4 directory on Windows.
