I recently hit this random error with the Microsoft AX Dynamics connector when try to configure the CRM org.
The following exception occurred while attempting to retrieve all
companies: Could not load type 'Microsoft.Xrm.Sdk.Client.IServiceManagement`1'
from assembly 'Microsoft.Xrm.Sdk, Version=18.104.22.168, Culture=neutral,
All I did to fix it was move the Microsoft.Xrm.Sdk.dll from the C:\Program Files (x86)\Microsoft Dynamics\Microsoft Dynamics Adapter\Adapters\Microsoft.Dynamics.Integration.Adapters.Crm2011 folder and copy it into the root folder for the dynamics adapter install.
It seems the installer may have not moved that required file and the configuration wizard is from within that folder.
