I am reposting this question in the right forum.
I download SP15 which was available last week of Dec. I successfully installed ABAP. When I extracted all the 4 rar files for java(which all had the same content!) and started my installation, after the initial screens in the SAP Java Cryptographic Toolkit screen, even though the crypto.sda is in the right directory I am getting file not exists for the SAP Java Library archive parameter. Any suggestions on how to overcome this or what I am doing wrong?
