Adaptive Server Enterprise 15.7 Developer Edition
any one knows where i can get the download link for Adaptive Server Enterprise 15.7 Developer edition for windows 64x?
You are right.
There is only ASE 16.0 available (latest version).
There is another way, through Home | SAP Support Portal (Download Software)
but you have to be SAP Customer (auth. with SAP User ID / Password ).
There is 15.7 version available for download.
