How do I download and install the free CSD-Community software Mercury and enCIFer?


You can download a small online installer for the CSD Portfolio for Windows, Linux or MacOS from our Downloads page. Running this installer will allow you to select the software and data you would like to install - for our free products it is recommended that you select the option "I would like to only install the free CSD-Community products Mercury and enCIFer". Click the Details link for the version you need for brief installation instructions. We recommend uninstalling older versions of Mercury/enCIFer and any other CCDC software before installing the current version, and on Linux you need to make the installer executable before running it.

Before Mercury or enCIFer can be run it must be activated. For the free version, go to the CSD-Community tab in the activation tool and click Activate. The activation tool should pop up automatically the first time Mercury or enCIFer is launched. It can also be run manually if required - its location depends on your operating system. Here <INSTALLDIR> refers to the directory where Mercury and enCIFer were installed, normally a CCDC folder in your home directory.
