Durango Interferometry Software is a free download. Use it to examine the
sample data files or to create your own synthetic data files. A data acquisition
license and data acquisition key are needed only to acquire new data with
your own interferometer.
You should download and install the Sentinel Protection Installer BEFORE attaching your Durango hardware key. If you have attached the key first, you should detach it and try uninstalling the Sentinel Protection Installer using Windows’ Add/Remove Programs (XP) or Uninstall Software (Win7) feature. Failing that, download and run the SSD Cleanup utility, reboot your system, and then run the key driver installer again. For additional help please refer to the Sentinel End-User Troubleshooting Guide.
