[wix-users] [WiX-users] SecureCustomProperties and Merge module

[Reuss, Matthias]

Hello,

I am aware that I am responding to a very old thread, but unfortunately I didn't find newer ones for this topic.

First of all: I do not think a type 51 custom action will not help to make those properties that have been declared secure in the merge modules really secure. This is because of timing:

SecureCustomProperties must be evaluated at the time the MSI is opened (because they determine which command-line parameters are accepted), whereas any type 51 CA is executed much later (in the sequences).

At this evaluation time, SecureCustomProperties is the "original" string regardless of whether or not a type 51 CA will modify it later.

I too consider this behaviour to be a bug, since it prevents defining command-line-settable
 Properties in a merge module.

Best regards

Matthias

Betreff: [WiX-users] SecureCustomProperties and Merge module

Hello,

I declare a property in a merge module and mark it as Secure. However, when the final MSI is built , i observe that  the property is not appended to the SecureCustomProperties in the Property table.

As per the following  pages:
http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/SecureCustomProperties-from-Merge-Module-td709878.html

http://sourceforge.net/p/wix/bugs/2295/
http://forum.installsite.net/index.php?showtopic=15935


this is not supported by windows installer.

I have also read that the above can be achieved by making use of a type 51 custom action.
Can anyone elaborate on this approach?

Any help would be very much appreciated.

Regards,
Kiran Hegde
