hi Corinna,
SncInit(): Initializing Secure Network Communication (SNC) AMD/Intel x86_64 with Linux
Please download this SAP Cryptographic Library Linux for X86_64 (AMD64) from service.sap.com and replace in saprouter\crypto\
Issue is , for 64bit sapcrypto is required for 64bit saprouter and right now, SAProuter initialization fails because 64bit saprouter binary can not load the 32bit libsapcrypto.so.
Regards,
