Huygens Software Installation Instructions

This page contains the installation, update, and removal instructions for the Huygens Software suite.


Download the Huygens suite from the Download page.
  • Windows
    • Double-click the downloaded .exe file to start the installation. By default Huygens will be installed in C:\Program files\SVI\ but you may specify a different installation directory if necessary.
    • If you encounter the message Windows protected your PC on Windows 8, please follow the instructions in Windows 8 Installation.
    • Huygens is fully compatible with Windows 10
  • Linux
    Huygens will be installed in /usr/local/svi, with symlinks to the executables in /usr/local/bin. Any old versions will automatically be upgraded.
    • Debian-based systems:
      • Simply double-click the downloaded .deb file and the Huygens Software suite will be installed using the package manager.
      • Alternatively, you can install the software using the terminal; go to the directory where you downloaded the file and execute (change the filename to the file you downloaded)
        sudo dpkg -i huygens_14.10.2-p3_amd64.deb
    • RPM-based system:
      • Open a terminal, go to the directory where you downloaded the file and execute (change the filename to the file you downloaded)
        yum install huygens-14.10.2-p3.x86_64.rpm
  • OS X
    • An X11 server such as XQuartz is required. Download XQuartz here or see our X11 page for more information.
    • Double-click the downloaded .pkg file to start the installation. Note that only users with administrative privileges can install applications in the default destination. If you want to install the application in a directory different to the default one (because you are beta-testing a new release, or because you do not have enough permissions, for example) specify the destination directory while you use the installation wizard.

Adding a license/ enabling your Huygens Everywhere subscription

Start the application by clicking its icon. Without a license the software will open in freeware mode and display the start-up window. Follow the instructions on the license string page to obtain and add a license string or to log in.


Download the new version from the Download page and proceed with the installation as explained above. Do NOT uninstall the old version as this will delete the file containing your license strings. On OS X, make sure you make a backup of the license string in a safe place before you remove the previous installation.


Uninstalling the software will also cause your license string to be removed. If you prefer to uninstall your current version prior to installing a newer one, be sure to store your license string in a safe place.
  • Windows:
    • Open the software the Control Panel (Windows 7,Windows 8 and 10) and click Programs and features, then click the Huygens software to uninstall it.
