-> "Browse our Download Catalog"
-> "SAP NetWeaver and complementary products"
-> "SAP NetWeaver"
-> "SAP NetWeaver 7.5"
-> "Installation and Upgrade"
-> Select your operating system
-> Select any database, then scroll down to bottom of page (for example, Microsoft Windows )
-> Download "SAP Kernel 7.45 Windows Server on x64 64bit - NW 7.5"
