QT Installer framework custom script
I'm creating an installer with several components in it (com.1 ; com.2 ; com.3). For a particular component (com.1), I would like to check if a folder exists or not, before starting installation process for this component. If the folder exists, prompt the user with a message and give him the choice to Retry or Cancel the installation.
Someone can help me to start with this?
Thank you very much in advance.
