Same experience for me.
I downloaded/installed a NPL-NetWeaver for Linux, it is up and running within a vmware-box. I got a 90-trial-license from SAP. The NetWeaver is up and running.
Before I can use this installation I need to install the license file, transaction "slicense".
But to install the license-file, I get an error "sapcrypto lib is missing".
So I would like to download it from service.sap.com. But I can't, since I do not get an user account without an installation number. Sic.
