1. Open the FixMain.vb main form.
2. Drop a Button on top of the MainHeaderControl1 ex: Button1.
3. Add the following code to the FixMain form:

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
      ShowSecurityDialog()
End Sub

 Private Sub ShowSecurityDialog()
      Dim showPermissionFlag As Boolean = False
      Dim showRestrictionSetsFlag As Boolean = False
      If MicroFour.StrataFrame.Security.SecurityBasics.CurrentUser.IsAdministrator Then
          showPermissionFlag = True
          showRestrictionSetsFlag = True
      End If
      '-- Create the form and show it
      Using loDialog As New MicroFour.StrataFrame.Security.SecurityDialog(showPermissionFlag, showRestrictionSetsFlag)
          loDialog.ShowDialog()
      End Using
End Sub

Now run the application and login with the current credentials then click your button and the Security Editor will show up.
You will have no data there since there is no really a Security metadata shipped with StrataFlix, but you can create users
and roles and then test if you can copy those roles as in your real application.

Hope this help you figure out your issue.

1. What OS version are you using?
2. Take a look at the MicroFourxxxx assemblies in the C:\Windows\assembly\ and check let me know what is the version listed, it should be 1.7.0.0 but when you check the File Version in the properties of any of the files it should say 1.7.7.1
