The '2016 R1' SDK and SDKs older than 2016 R1 have had their downloads removed because Intel identified security vulnerabilities. '2016 R2' is now the oldest SDK that you can download. You can download it using this link: http://registrationcenter-download.intel.com/akdlm/irc_nas/vcp/9078/intel_rs_sdk_offline_package_10.0.26.0396.exe
