Assume that you have Microsoft BizTalk Server 2013 and Microsoft BizTalk Enterprise Service Bus (ESB) Toolkit 2.2 installed on a computer. When you try to use the ESB configuration tool to configure the Microsoft Enterprise Single Sign-On (SSO) configuration source, the configuration fails. Additionally, you receive an error message that resembles the following:

Exception calling "Load" with "1" argument(s): "Could not load file or assembly 'Microsoft.BizTalk.Interop.SSOClient Version=, Culture=neutral, PublicKey Token='31bf3856ad364e35' or one of its dependencies. The system cannot find the files specified."


The issue occurs because of incorrect file dependency. BizTalk Server 2013 installs the Microsoft.BizTalk.Interop.SSOClient Version=7.0.2300.0 dll. However, ESB Toolkit refers to the 'Microsoft.BizTalk.Interop.SSOClient Version= dll. 

Note After you install this cumulative update package, ESB Toolkit will refer to the correct version.
