my problem is that I have four properties and i want only the first property
to be selected and installed by default (so the user can't deselect it).
when i used the property "Required" , once i deselected the other three
I have noticed that i can deselect the first property too,
shortly, i need to find the property where i can declare of a feature to be
installed by default (so the user can't deselect it) without any depend on
other features !!!
