Hello and welcome to Advanced Installer forums,
Thank you for your interest in Advanced Installer.
In order to achieve what you want you can use our
INI files support. For example you can go in "Dialogs" page and add an edit box control associated with an IP_PROP
public property. Then, you can go in "Files and Folders" page and create from scratch your INI file (using [New INI file] toolbar button) or you can import the INI file (using the {Import Files -> Import INI] button). Finally you can edit the "ip"
entry value of your INI file to use the IP_PROP property.
Also, I've attached a sample created with version 11.1 of Advanced Installer, which implements a similar scenario.
Please keep in mind that you need at least an "Enterprise" project type in order to implement this scenario.
All the best,
Daniel
