Licensing - Finding Your MAC Address


  1.  First ensure you find the MAC address of the correct computer
    • If this is a locked license it will simply be the system you want to run the software on
    • For floating licenses you will need to decide on a machine which will run the PTC license server
  2. Once you have established this, launch the ‘Network and Sharing Center’ from either your system tray or the ‘Control Panel’
  3. Go to ‘Change Adapter Settings’ which will list the network devices connected to your computer
  4. Make sure you select the network device which is for the Ethernet port rather than your Wi-Fi.
    • This is because Wi-Fi adapters can be easily disabled which will cause your license to fail
    • Some users will have ‘Virtual’ network ports which do not physically exist on the computer. Do not select when finding your MAC address.
    • If you have multiple physical Ethernet ports it doesn’t matter which one you choose.
  5. Right click on the Ethernet port and choose ‘Status’
  6. Go to ‘Details’ and find the ‘Physical Address’ in the format 00-00-00-00-00-00
  7. Make a note of this address as it will be used to generate your license file

Why do I need to know a MAC address to create a license?

Every PTC license is assigned to a computer. To be more specific the license is tied to a specific network device on the machine, e.g. an Ethernet port. Every network device has a unique address which is used to identify your computer system. This address is commonly known as a MAC address, CPU ID or Physical address. It is this address which is written into your license file to authenticate the software is being used on the correct computer.

Command Prompt Method

Some users may be more familiar opening a command prompt to run ‘ipconfig /all’ which generates a list of connected network devices. If you use this method be sure to select the correct device.
