Activating a license

Once you've installed the software, you need to activate your license. Please follow these steps:

  1. Locate your activation code, which looks like “GXXXXXX-XXXXXXXX”
  2. From the Windows Start menu, select “Geochemist's Workbench” to launch the GWB dashboard
  3.    For ChemPlugin, navigate to the installation directory (e.g., “\Program Files\ChemPlugin”), move to the “License” subdirectory, and double-click on “activate.exe”. Then, proceed to step 4.
  4. Move to the Support tab and click Activate GWB
  5. Paste your activation code in the space provided and click Activate. If you've previously activated a different license, click New... before entering the code If successful, your license will show status “activated”
  6. Close the activation utility
  7. The dashboard shows which package is activated and what apps are available to use

   Upgrading or renewing your subscription? Be sure to activate on the same machine running the previous license. If the previous license is installed on a different computer, you need to deactivate from the old computer and activate on the new machine, either before or after applying the upgrade.

   You can activate more than one license at a time. If you are running GWB Standard and wish to activate a trial license for GWB Professional, for example, there is no need to deactivate the original license.

Deactivating a license

  1. Open the GWB Activation Utility, select the license, and click Deactivate
  2. The status changes to “not activated”

   Uninstalling the software does not deactivate your license. If the software has been uninstalled, you need to reinstall in order to deactivate.

   Fixed-node licenses can be moved up to twelve times per year to cover maintenance needs before requiring a reset from GWB support.
