It has been reported in some rare cases that the installation of SNAP components from within the installer fails due to download errors. This happens for several reasons, problems with internet proxy, restrictive firewall settings or general connection problems. Therefore we now provide all toolbox components in one archive for download. Note this is only optional. In general you can rely on the download within the installer. However, providing these components also allows users to put everything on a DVD or USB-Stick and install SNAP and the Sentinel Toolboxes on a system without internet connection. The archive file is provided on the download page.
