Manual steps:


Refer to the following PDF for instructions:mgc_licen.pdf


Automated steps:




To run the Mentor License Utility to automate the installation:


  1. Download the "Full"  version of the Mentor License Utility from SupportNet
  2. Run the Mentor_License_Utility_INSTALL.exe which extracts all the program files, creates a shortcut*, and launches the Mentor License Utility program. (See README.txt for version information)
  3. Click the Install License button (bottom right corner)
  4. Select the Install a Nodelocked or Floating license to this machine option
  5. Follow the remaining prompts to complete the license installation


* A shortcut to the Mentor License Utility is created under Start > Programs > Mentor Graphics License Utility


Note: If licensing errors are encountered after running the Install License to set up the license manager: Run a diagnostic report from the Tools > Create Diagnostic Report > Standard menu option, and attach the resulting diag_file.txt to a new Service Request on SupportNet, to expedite the troubleshooting process.



The Mentor License Utility automates the license server configuration tasks, including:


  • Separation of Nodelocked/Floating licenses by HostID (you don't need to separate license file manually)
  • Installation of hardware key drivers (if necessary)
  • Installation of PCLS / license server software (if necessary)
  • Creation of license manager (as a Windows/Lmtools service, and as "automatic")
  • Updating of existing license manager service with new licenses
  • Pointing clients to the server via port@host value
  • Setting the MGLS_LICENSE_FILE environment variable


Note: The Mentor License Utility only supports licenses under the Mentor Graphics Vendor Daemon ("mgcld")
