Librfc32.dll version 4.6C, which is part of the SAP RFC Software Development Kit (SDK), must be installed on all the machines on which Siebel Tools and Siebel Server are installed. If you receive this error message, it may be due to a missing librfc32.dll file or a file that is an earlier version than 4.6C. This may happen if you have not installed the librfc32.dll from SAP. This can be installed during installation of the SAPGui by selecting the Development Tools check box.

The Siebel applications look for the librfc32.dll file in the SYSTEM32 folder of the Windows NT or Windows 2000 installation. The product version of this file should be 46C. To check the Product Version:

  1. Select the file in Windows Explorer.
  2. Right-click, and choose Properties.
  3. Select the Version tab and the Product Version item in the list box.
