InstallScript MSI Project - Custom Action as dialog result

Question

Hi,

I have an InstallShield - InstallScript MSI project and a custom action defined that calls a method from a dll. I can't seem to find a way of running this custom action as a dialog result, for example when the installation is finished and the user hits Finish button.

Any suggestions are more than welcomed.

Thanks.

Edit

I was not able to find a decent solution to this, so i've rewritten the custom action as a method in InstallScript. This can easily be called when a dialog is closed.
