To Whom It May Concern
When you add the Prerequisites actions, you get 2 additional scripts into the MsiCode:
The first is for checking thr prereq' and the second is for installing the prereq'.
if you don't want to install the prereq', and just to display a warning, you should REMOVE
the second script line from the code flow.
if not, the package of the prereq' will be added to the project output package and increases it's size.
hope this will help.
