First the disclaimer: I'm new to installshield, and vbscript, not new to scripting (go autoit!). I've got a feeling this is a real newb type question, and that I maybe should be posting in the Package Development forum (feel free to slap me if that's the case).

I created a vbscript custom action which checks for some registry keys and alters them if neccessary. In case a key could not be written or something like that, the setup should be aborted.

In order to achieve this, I set a property which I tried to use as a condition for the next step within the execute sequence but this does not work.

I found out that this can not work since the custom action cannot write the property at the time it is executed.

So the question is: How can I achieve an abort of installation depending on what my custom action says? Is there a method to pass an 'abort installation request' to the Installer or something like that?

You should need return 3 from your function for a fail and 0 or 1 for success.

Here is a msdn article on the topic : http://msdn.microsoft.com/en-us/library/aa371254(VS.85).aspx

Make sure you put your script in a function.
