Installing the GWB

MS WindowsYou can install The Geochemist's Workbench® 2021 Professional, Standard, or Essentials under Windows 10, 8.1, or 8. The vast majority of users should install the 64 bit, rather than the 32 bit version.

Many of our users run the GWB on a Mac. Please see our tips for Mac users.

You should have a Pentium or later processor, approximately 4 GB of memory, and about 200 MB of available disk space.

When you purchase a software license or upgrade, you will receive a download link and activation code. Download the installer, double click on it, and follow the directions on your screen. To activate, start the GWB dashboard and paste in the activation code when prompted. Trouble? Please check the list of resolutions to common issues.

If you are upgrading, GWB 2021 installs on top of your existing installation. Do not uninstall the previous release.
