apsncencryption.dll is not a valid Win32 application

[shail_verma]

Hi All,

Need some help around integrating a .NET application with S4 HANA when SNC is activated. Our code uses SAP NCO X64. We installed SNCCLNTCRYPT00_3-80002731.

When we are trying to make a call to SAP S4, we are getting "apsncencryption.dll is not a valid Win32 application". We realize that instead of 64 bit, the application is calling 86 bit library. Here is the message .

LoadLibrary("C:\Program Files
(x86)\SAP\SNCEncryption\x86\sapsncencryption.dll")
Error 193 = "C:\Program Files
(x86)\SAP\SNCEncryption\x86\sapsncencryption.dll is not a
valid Win32 application."

Here is the complete log.

SAP.Middleware.Connector.RfcCommunicationException: '

Any help is appreciated.

The x86 libraries (86 as Intel 8086 processors family, not bits) are for 32 bit operating systems and the x64 libraries are for 64 bit operating systems.

• Choose correct version to download
• Look at OSS notes such as 2425150 - Release Note SNC Client Encryption 2.0 or 2440692 - Central Note for SNC Client Encryption 2.0
