In this article we review what you should consider when upgrading your license manager to lmadmin 2021.4.

Before You Start

  • lmadmin is the license manager program used by GeoStudio to serve network licenses. 
  • Although lmadmin is developed by Flexera, GeoStudio uses a unique implementation of lmadmin. 
  • lmadmin 2021.4 is our current supported version.  
  • The minimum server OS requirement to run lmadmin 2021.4 is Windows Server 2016. 
  • Installations on older operating systems are not supported.
  • lmadmin 2021.4 is capable of serving all GeoStudio licenses, including licenses for legacy versions that are no longer supported.
  • If you are using network licensing with GeoStudio 2021.4, you will need to upgrade to lmadmin 2021.4.  GeoStudio 2021.4 cannot be served licenses from earlier versions of lmadmin.

Download lmadmin

  • Please contact support with your serial number to request a download link to the license manager.

System Requirements

Minimum System Requirements

  • Microsoft® Windows Server® 2019, Windows Server® 2016.
  • Microsoft® .NET 4.0 will be installed automatically if it is missing.

License Activation

  • An Internet connection is necessary for online activation licenses.
  • Ensure your firewall allows access to licsvr.geoslope.com and activate.geoslope.com.

Supported Virtual Machines

The latest release of lmadmin can be run on these VM platforms:

  • VMware® ESXi™ 6.5 or 6.7
  • VMware® Workstation™ 16.1.0
  • Microsoft® Hyper-V® on Windows Server® 2019 or Windows Server® 2016 or Windows® 10
  • Citrix® XenServer® 8.0

Upgrading on the Same Computer

  • lmadmin 2021.4 does not do an in-place upgrade.  You will need to uninstall your existing version of lmadmin first.
  • After uninstalling the previous version, simply install the new version.
  • Uninstalling / re-installing lmadmin may require a system re-start.
  • If you have any activation licenses on the computer, you may get a warning about them when uninstalling the previous version of lmadmin. 
  • If you are upgrading from a 32 bit version of lmadmin, you will need to return your activated licenses before proceeding.
  • You can ignore these warnings and proceed with the uninstall as long as you are upgrading from a 64 bit version of lmadmin and you are going to re-install lmadmin 2021.4 on the same computer.
  • Regardless, we strongly recommend returning your activated licenses before upgrading, and re-activating them afterwards.  This will avoid any unforeseen problems with activation licenses. 

Upgrading to a Different Computer

  • Set up the new license server first.  Ensure it meets the minimum system requirements for lmadmin 2021.4.
  • Install lmadmin 2021.4 on the new server.
  • If your licenses are Activation licenses:
    • On the old license server, start the LicenseInstaller application and choose the option to 'Move Licenses'.
    • Take note of the serial numbers you will be returning.
    • Initiate the return process and return all of your activation licenses.
    • On the new license server, activate the returned licenses using the LicenseInstaller application.
  • If your licenses are node locked to the HostID of the computer:
    • Run GeoMedic on both the old and new license server.  This will create a diagnostic report file for each computer.
    • Create a ticket in the GeoStudio Support Portal and attach the diagnostic reports in your ticket to request having the licenses moved to the new server.
    • GeoStudio technical support will advise you when the changes to the licenses have been completed.
  • After the new license server is running, re-configure your GeoStudio clients to point to the new license server.
