title: .NET Runtime Error Event Id 1026
body: <p>I have a WPF application I have created on a Windows 8.1 machine targeting .NET runtime 4.5.1.  It runs fine on the development machine.</p>
  
  <p>I am trying to install it on a Windows 7 machine. It has .Net 4.5.1 installed. When I try to run it on the Windows 7 Machine the login window comes up. When I enter the password, the application verifies the password then it crashes. I have verified that it is connecting to the server to verify the password...so it's not a SQL Connection error.</p>
  
  <p>So it appears that it happens when the main application windows is trying to display. Here is the info that gets recorded in the Application log. Notice the framework version. The app is targeting 4.5.1. So I don't understand why it is showing 4.0.30319.</p>
  
  <pre><code>Application: HardwarResources.WPF.exe
  Framework Version: v4.0.30319
  Description: The process was terminated due to an unhandled exception.
  Exception Info: System.Data.Core.EntityCommandExecutionException
  Stack:
    at System.Windows.Window.ShowDialog()
    at HardwareResources.WPF.MainEntry.Main(System.String[])
  </code></pre>
  
  <p>The only other pertinent information is Event ID: 1026.</p>
  
  <p>HELP!</p>
