Firstly, you shouldn't be calling Application.Run yourself - you should only have the one message loop. I'm not sure what effect that would have, since there can only be one MainWindow object, and that's already in use ... if that worked (which it doesn't) then your thread Abort would either kill the main form and app, or possibly make it impossible to exit the main process properly at all.

Secondly, you can't update a control except from the thread on which it was created - normally the one and only UI thread - so accessing the label on the splash form is going to be problematic - if you could find it, which you can't since the only reference you have is local to the loading method.

The normal way to do this is to Show the Splash screen, and move the long running task to a background thread, which updates the splash screen via progress reports to the UI thread - and I'd move the "loading" code into the Form.Load or Form.Shown event handlers instead of in the main form constructor and use a BackgroundWorker class instance to offload the long job to a second thread, using the Progress reporting of that class to get information back to the UI thread.
