They are still two separate items. SecureCustomProperties is need if you want
to pass properties from the UI to the execute sequence, whether they get passed
to custom actions or not. If you pass them to a immediate custom actions
there's no need to use CustomActionData. So if you wanted to collect a property
value in the UI sequence AND pass it to a deferred custom action then you'd
need to use SCP to get it into the execute sequence AND use CustomActionData to
pass it to a deferred custom action.
You might be thinking that CustomActionData is a single property, but it's not.
Every deferred custom action can have its own CustomActionData associated with
it. Yes, it's used to pass property values into deferred custom actions. You
simply cannot directly get property values in deferred custom actions, that's
what CustomActionData is for.

Vista
Since both worked in my scenario, I still, really don't know the
difference.
When you say SCPs is used to pass property values to the execute
sequence, does that include access during or for deferred custom
actions? Or, is CAD used to pass information to the deferred actions?
Would there be a good example to illustrate the need for the use of
CustomActionData where simply adding a property to
SecureCustomProperties would not provide access during the deferred
sequence?
Any further help greatly appreciated.

Briefly, CustomActionData is a parameter passing scheme to get property
values passed to a deferred custom action. SecureCustomProperties is a
list of properties that you want to pass from the UI sequence (where you
probably collected their values) across the context boundary into the
execute sequence.

Action on Vista
So what exactly is the difference between SecureCustomProperties and
CustomActionData? I still do not fully understand this.
We have a public property that holds a string that we write to the
registry
in certain cases. Is is held in the Property table. Let's say it
contains
8.1.2.3 and is called OURVERSION.
I have a little widget that runs near the end of the install that tests
the
condition for the registry edit and edits accordingly. I used a Set
Property custom action sequenced in the Immediate Sequence to set the
above
mentioned property to something like PASSDATAACTION.
Then, in the Deferrec Sequence action, I reference CustomActionData that
now
holds the value I passed. All seems to work OK here.
I then thought, lets add the original property, OURVERSION, to
SecureCustomProperties and just reference that directly as a parameter
in my
Deferred action, guess what. This works too.
So, I'm unclear as to the true purpose of each.
I know this really is off WiX topic, but I've gotten great help here
before
so any now is greatly appreciated. The scenario described above may not
be
exactly what is going on, but just to give an example.
Thanks in advance for any help!!
