The Action Designer in combination with Event Handlers is a powerful feature of Lizajet Installer. With the Action Designer you can synchronize the installation of multiple packages.
At each Action you can define up to 6 event handlers and an associated Dialog.

What must be done:
In the example we show a Package for installing the Oracle Client. Before installation we must first of courese check if the Oracle Client is maybe already installed, and if it is already installed we can stop with installation. We also do not need to download the huge Oracle Client files. In the first Action we have defined an Event Handler that executes this check using Object Pascal Script.

If you want to try it yourself
If you want to try the same installation yourself, you must download the Oracle Client package. We do not include the Oracle Client files themselves, you need the Oracle Client CD for creating the full installation.
