This is likely caused by a Microsoft.Net Framework 2.0 issue.  If your System.data.ni.dll file is less than 2.0.50727.1813, then you need to update the Microsoft.Net Framework version on at least your Microsoft CRM server and also your Microsoft SQL Server.  You can get the update in KB article, https://support.microsoft.com/kb/948815 .  The problem is described in the KB article, https://support.microsoft.com/kb/948868 .
