--- Comment #2 from James Hawkins truiken@gmail.com 2008-05-02 22:51:26 --- Starting with creating the WelcomeDlg dialog:
event.c:56:event_do_dialog dialog.c:3466:msi_dialog_create dialog.c:3553:msi_dialog_run_message_loop r = SendMessage(MsiHiddenWindow, WM_MSI_DIALOG_CREATE, 0, dialog) dialog.c:3446:MSIHiddenWindowProc (the MsiHiddenWindowProc should get this message and call msi_dialog_run_message_loop in the correct thread, but the MsiHiddentWindowProc never gets this message) r == ERROR_SUCCESS -> destroy_dialog
