Hello,
From what I can see in your screenshot, I'm assuming the prerequisites are added as
pre-install prerequisites.
Is there possibility to have some interaction with prerequisites selector ? TO get checked items or number or something?
Unfortunately, it is not possible to achieve this with pre-install prerequisites.
It is, however, possible to do so with
feature-based prerequisites. As the name suggests, for each feature-based prerequisite, a feature is created in the
"Organization" page. We can use the
state of the feature in order to condition your custom action that displays the message.
For instance, a condition as it follows can be used:
- condition.png (29.41 KiB) Viewed 2559 times
The above condition can be translated to:
Feature will be installed local. The feature is not reinstalled.
Unfortunately, not all prerequisites can be added as feature-based (due to some liminations regarding the complexity of the package). For instance, .NET Framework can not be installed as a feature-based prerequisite.
Hope this helps somehow!
Best regards,
Catalin
