Problems when SSIS package is running in background

Jun 24, 2014 at 8:15 AM
I am facing the Problem that the SSIS package using GAS is only running in "user mode". When I schedule that package for Background processing I receive the following error message:

get Visits:Error: System.InvalidOperationException: Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.
at System.Windows.Forms.Form.ShowDialog(IWin32Window owner)
at SSISComponents.Authenticator.Login()
at SSISComponents.GoogleAnalyticsSource.PreExecute()
at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostPreExecute(IDTSManagedComponentWrapper100 wrapper)

Any idea how to handle this?
Thank you
