SNC File Not Found

Symptom

When you try to sign in to an SAP system that has SNC configured, an error message similar to the following is displayed.

SNC file not found

Cause

This problem occurs when the SNC LIB file that Process Runner uses is not available in the default path or there is no environment variable set on your computer referencing the SNC LIB file.

Solution

This issue can be resolved by configuring the correct SNC LIB path. This file is named sncgs32.dll, gssapi32.dll, sapcrypto.dll, or sapsncencryption.dll, and can be found at C:\Windows\System32.

To add an Environment or System Variable to your machine, contact your SAP Basis team.

To find and configure the SNC LIB path,

1. Open the Command Prompt window and run the SET command.
2. If you find the SNC LIB file name and its path, copy the path and perform the following:
   1. Open Process Runner.
   2. On the HOME tab, select SAP Shortcuts. The Connector for SAP window appears.
   3. On the Advanced tab, paste the SNC LIB path under Other Config File section.
3. If you find only SNC LIB file name, perform the following:
   1. In the Command Prompt, run the <SNCLIBFileName>/s/a command. The path of SNC LIB file is displayed. Perform this step using all four names (sncgs32.dll, gssapi32.dll, sapcrypto.dll, and sapsncencryption.dll), until you find the path of SNC LIB file.
   2. After you find the path of SNC LIB file, copy the path and perform the step 2a, 2b, and 2c.
