Application.Exit() SF 7.0

[newthom]

Does anyone know what is the matter using this command?
It is ignored until all commands on the particular Action tab have run.
I need something that immediately halts installation right when certain conditions are encountered.
Thank you, any hint would be much appreciated.

So you're saying that this yeilds a dialog box:

Application.Exit(0);
Dialog.Message("test","After Application.Exit(0);");
Because it doesn't for me... I tried in on startup, preinstall, and onnext of a screen....
