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.

Subject: Re: [WiX-users] Command Line Parameters to Deferred CustomAction on 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. -----Original Message----- From: Wilson, Phil [mailto:phil.wil...@invensys.com] Sent: Tuesday, September 21, 2010 5:17 PM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Command Line Parameters to Deferred CustomAction on Vista 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.

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.
