Certificate Manager Config Wizard: Installation error

Hi,

i am installing Certificate Manager Config Wizard (Microsoft Identity Manager 2016) and after clicking Configure at the end of the wizard i get the following error message:

************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an object.
   at Microsoft.Clm.Config.Core.ConfigHelper.RequireSSL(String applicationName)
   at Microsoft.Clm.Config.Steps.Summary.NeedConfigureWebSite()

   at System.Windows.Forms.Button.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

I have implemented SSL for the Web Portal in IIS (no error message there, but a certificate security warning when i try to open the default website).

Thanks.
