Vise X Problem

[uriaf]

Hi all,
I'm using vise x to create a setup file for an app.
I have a problem that I don't know how to solve.
When I quit during installation I get an Error message instead of just close the installation.

I downloaded another setup file from the internet and noticed when I stop the installation in the middle it just closes it.

Does anybody know how i can get the same affect?

Thanks!!
